Inswing Width Measurements

The width of an exterior door unit is dependent on three things: configuration, unit construction, and door swing.

The configuration of the unit corresponds to pieces and parts of the unit. If a unit is a single entry door, the width will be much smaller than a triple patio door. The more components used to create a unit will result in a wider unit.

Construction relates to a continuous or boxed unit when referring to doors with sidelites. Most units are continuous, meaning they utilize a single head jamb and a single sill. A boxed until will be constructed of separate units coming together. One of the benefits of a boxed unit is the ability to include mull pockets which makes the unit even wider in the scenario that a standard unit will not fit in the rough opening of the building.

The swing of the unit is the final factor of the unit width as the brickmould sits different on an outswing unit than it does on a inswing unit, resulting in different dimensions.

Component Sizes

While every unit type needs different components, the size of the components are typically the same.

An exterior jamb measure 3/4″ (in the rabbet).
An astragal measures 7/8″.
A standard mullpost measures 1″.
A fat boy mullpost which is used in venting sidelite units measures 1-1/2″.
Standard brickmould is 2″.
Most units also require clearance on the hinge and strike side of a door and this will range by construction type.

Measurement Types

There are four measurement types associated with units.

Unit Dimension (UD) is the measurement of the unit from the outside of the left jamb to the outside of the right jamb.

Brickmould Dimension (BD) is the measurement of the unit including the brickmould from the outside of the left brickmould to the outside of the right brickmould.

Rough Opening (RO) is the unit width dimension plus 3/4″ to account for installation of a unit into a building’s rough opening.

Masonry Opening (MO) is the brickmould width dimensions plus 1/2″ to account for the installation of a unit into a building’s masonry opening.

Primed Stile and Rail Panel Types

One of the features of a stile and rail door is the type of panel. There are single hip raised and flat panel doors to fit any home design.

Single Hip Raised Panel with Ovolo Sticking

A single hip raised panel is a traditional panel design that has been a staple in homes for years. Single hip raised panels for interior doors are all available with ovolo sticking.

Transoms

A transom is the entity found above the door in a door unit. It provides an additional opportunity to allow natural light into the home. Transoms can be referred to as direct set or sash set and are available in a variety of shapes.

Transom Unit Anatomy

A transom unit consists of the transom surrounded on all four sides by a frame. The side and head jambs are standard jambs while the base jamb has a sloped sill. Both wood and composite frames can be used to create a transom unit.

Door units with sidelites that are continuous typically have a continuous transom unit – or one unit above the door unit. When a door unit with sidelites is boxed however and a transom is desired, the transom must be boxed a well. A door with two sidelites will have three transoms above it – one over each sidelite and one over the door.

Transom Size

A typical standard height of a transom unit is 13-1/2”. This includes a transom that is 12” in height and a surrounding frame that measures 3/4” on all sides. The weight of the transom on top of a double door unit may cause the transom to sag in the middle adding stress to the door unit. Therefore, double doors will use a reinforced transom which adds a 1” reinforcement piece making the transom only 11” in height. For more information on reinforced transoms, please click here.

Direct Set Transom

Direct set transoms refer to a piece of glass that is directly set into the transom frame. It is stopped and caulked into place to help seal against the weather.

Fiberglass and Steel door units typically are accompanied by Direct Set Transoms.

Sash Set Transom

Sash set transoms refer to a piece of glass that is surrounded by wood or vinyl components and then set into the transom frame. The entire sash is stopped and caulked into place to help seal against the weather.

Wood door units typically are accompanied by a Sash Set Transom. The stile of the sash will line up with the door stile or the sidelite stile depending on the door configuration.

Shapes

The various shapes of transoms include rectangular, elliptical, and half round transoms in different glass styles.

Rectangular

Elliptical

Half Round

Special Order Transom

Not all openings were made to the standard. There are times when we need to special order glass or an entire transom to accommodate the opening. While a standard transom height is 12″, they can be crafted up to 24″ but nothing larger.

If you know the Unit Dimensions, you can figure out what size transom to order. To find the width, take the unit width and subtract 1-1/2” to account for the transom frame. To find the height, you have to subtract the door unit height from the overall unit height. For example, when the overall unit height needed is 102”, however a 7/0 door unit is desired which has a unit height of 86”.

102” Overall Unit Height – 86” Door Unit Height = 16” Transom Unit Height – 1-1/2” Transom Frame = 14-1/2” Transom Height

If you know the Rough Opening Dimensions, you can figure out what size transom to order. To find the width, take the unit width, subtract the rough opening adder and 1-1/2” to account for the transom frame. To find the height, you have to subtract the door unit height and the rough opening adder from the overall unit height. For example, when the overall unit height needed is 102.5”, however a 7/0 door unit is desired which has a unit height of 86”.

102-1/2” Overall Unit Height – 86” Door Unit Height – 1/2” RO Adder = 16” Transom Unit Height – 1-1/2” Transom Frame = 14-1/2” Transom Height

Barn Door Hardware

Barn Door Hardware is a track and hardware system. Barn door hardware is attached to a door and used with a track to create a sliding door. It consists of a hardware mount that rolls along a track attached to the face of the wall. There are two kinds of mounts: a top mount attaches to the top of the door, and a surface mount attaches to the side of the top of the door.

The three common options are Standard Series, a Multi-Family (MP) Series, and a Stainless Steel Series. The standard hardware should always be offered first due to ball bearings, the ability to hold doors up to 400lbs and the powder coat finish. The MP Series has a thinner gauge hardware and is more similar to what box stores would carry as an import hardware set.

Barn Door Hardware adds an aesthetic look to a room while providing sliding functionality. This hardware is mainly used with a track to create a sliding door that divides two rooms. The finished opening depends on the configuration used. Please refer to the installation instructions for more information. All Finished openings can be found in the installation instructions for each hardware line.

Primed Stile and Rail Louvers

Louvers provide a way to have ventilation while maintaining privacy. Because the louvers are angled, there is a side where you cannot see into the next room and a side where you can. The side where you cannot see into the next room is called the blind side. It is important to note which side the blind side should face.

Pocket Door Hardware

Pocket Door hardware is installed inside the studs of an unfinished wall so the door can tuck into the wall when closed. Pocket Door Hardware is used when there isn’t room for a swinging or sliding door. It can be used often as a bathroom door.

Single Pocket Door Configuration

Converging Pocket Door Configuration

Pocket Door Hardware are from LE Johnson: the 1500 Knocked Down Series, the 2711 Pre-Assembled Series, and the 2710 Pre-assembled series. The 1500 series is avialable in a wide array of sizes but is also notched for proper field trimming for uncommon standard door sizes. The 2710 and 2711 series make it easy to install as the frames are already built and ready to go into the wall. The options for sizes are limited for these as Reeb only stocks a 6/8 height option.

Pocket door hardware kits work with 4-9/16″ jamb depths, but other jamb depth sizes are available as special order. Typical pocket door hardware is set up for a single door application, but by using a Converging Kit, it can also be set up for a double door application.

SOSS Hinges

SOSS Hinges are commonly referred to as an “Invisible Hinge” due to the lack of visible hinge barrel when the door is closed. They are found in many applications where flush fit, compact size and smooth operation are necessary features. Due to their size and thickness, these hinges must be used with a 5/4 interior flat jamb. They work best with solid core doors with double wood stiles, stave core doors, and stile and rail doors. Hollow core doors are not recommended with these hinges due to the construction.

There are two versions of the SOSS hinge: the #216 for 1-3/8″ doors and the #218 for 1-3/4″ doors. They are available in the following finishes:

US10BL – Oil Rubbed Bronze Laquered
US15 – Satin Nickel
US3 – Bright Brass
US4 – Dull Brass

Flush and Molded Doors

A flush or molded door is created by joining two skins by thin stile and rail components. In between is either a hollow core, a solid particle core, or a solid wood core each with its own benefits.

Molded Doors

Hollow Core doors offer a lighter-weight, economic alternative to wood stile and rail interior doors. They are available in a variety of designs.

Solid Particle Core doors provide added security and reduced sound transmissions while the heavier weight is similar to a wood stile and rail door. They are available in a variety of designs.

Flush Doors

Hollow Core doors offer a lighter-weight, economic alternative to wood stile and rail interior doors. They are available in a variety of designs.

Solid Particle Core doors provide added security and reduced sound transmissions while the heavier weight is similar to a wood stile and rail door. They are available in a variety of designs.

Structural Composite Lumber (SCL) Core provides added security, reduced sound transmission and are the heaviest, most durable construction type.

Bypass Door Hardware

Bypass door hardware allows for one door to slide in front of the other rather than swing open into a room or closet. This can be done with two doors to make a double door bypass, or three doors to make a triple door bypass. Bypass hardware is best for compact areas or small bedrooms that do not have the clearance for swinging door applications or when the customer specifically asks for it.

Double Door Bypass Configuration

Triple Door Bypass Configuration

A popular manufacturer of Bypass Door Hardware is LE Johnson. Bypass with frames should be ordered by the Rough Opening size. Bypass without frames should be ordered by the Finished Opening size.

Raised Panel Wood Blinds

Raised Panel style shutters vary from the classic louvered shutter. The Raised Panel is a solid wood shutter with no slats. It is joined with a mortise and tenon instead of dowel pins which allows for a two year warranty. It is a versatile solid white pine shutter that is smoothly sanded and ready for paint or stain.

Two equal raised panels are available with heights up to 6′-3″. Three equal raised panels are available in heights over 4′ 11″. The raised panel shutter design makes a classic addition to any home. They are not treated and not primed. Wood blinds are for decoration only and are not intended for hinging. All blinds priced per pair but are sold by the pieces. In other words, a quantity of 2 pieces will equal one set. Half sets are avilable and will be sold as one piece.

Layout dimensions based on a 3/0 x 4/3 are as follows:

Thickness 1-1/8″
Stiles 2″
Top Rail 2-3/8″
Intermediate Rail 3-1/2″
Bottom Rail 4-1/8″

Available in:

Width: 2/4, 2/6, 2/8, 3/0
