The Outswing Fire Sill has an all-aluminum construction to resist corrosion. It is recommended that all outswing units use NRP hinges. The sill is 1-1/4” Tall. Sill extenders are included with the frame’s closure package.

For best results, units with a public access or ADA sill should be used in a protected opening.
