Pemko STC411APK Full Mortise Acoustic Automatic Door Bottom, Mill Aluminum Finish

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. 

  • The acoustic automatic door bottom provides excellent performance for acoustic openings 
  • Independent testing has shown that the STC Series Automatic Door Bottom has "sealed-in-place" type performance
  • Meets ANSI Standard S12.60-2002, Acoustical Performance Criteria, Design Requirements, and Guidelines for Schools
  • Helps school projects earn LEED IEQ School Specific Credits for Enhanced Acoustical Performance
  • 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. 
  • End plate kits are included. Replacement part is K435. For doors narrower than 1-3/4", please specify K411 end plate kit. 
  • The drop-bar seal actuation mechanism (all models) causes the drop-bar seal to always actuate on the hinge side first. This feature prevents the seal from skidding along the floor / threshold while the door is being closed. Door hang up will not occur.
  • Pemko automatic door bottoms are provided NET length
