The Cortex Hidden Screw System hides unsightly screws, allowing the door unit to be installed in the rough opening with screws through the thickest part of the jamb for better long-term performance.
Each kit includes 10 Cortex screws, 10 On-Guard plugs, and 1 TORX screw bit that automatically sets the screw depth.
The hidden screw kit is available for Reeb Finish units with On-Guard frames. On-Guard Primed frames will use a smooth plug, while On-Guard Oak Grain and On-Guard Straight Grain frames will use a grained plug.
The plugs will be finished to match the finish of the frame. If an unfinished frame is selected, the plugs will remain unfinished.
For split finish frames, the plugs will match the finish of the thicker 1-1/4” part of the jamb. For Inswing units, this will be the exterior frame finish. For Outswing units, the plugs will match the interior frame finish.
