Pemko 4131_SL Automatic Door Bottom

Non-Handed, Surface and Semi-Mortise

  • 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 48".
  • 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.
