Non-handed, surface and semi-mortise models.
Smoother action positive seal mechanism. All Pemko automatic door bottoms consist of an aluminum case which surrounds a movable drop-bar seal. The drop-bar seal is actuated by a plunger which contacts the jamb as the door is closing, forcing the drop-bar seal down against the floor / threshold.
All models (except #430 and #412) are non-handed and reversible. Installation is fast and easy because disassembly is not required to change handing: simply flip the automatic door bottom and you’ve reversed the hand. The clean symmetrical square-shaped case design also provides for even flush mounting.
The 4131 can be mounted to either wood or hollow metal doors.
Screw applied end plates are provided for all mounting applications.
All Pemko automatic door bottoms seal up to a 3/4″ gap under the door except 420 and residential models which seal 1/2” maximum.
Available in any size ranging from 18″ to 72″.
All Pemko automatic door bottoms are provided NET length.
All Pemko automatic door bottoms can be trimmed down by as much as 2″ (stock lengths only). If non-stock sizes are ordered, order must note need to trim 2 inches from the size ordered.
