Pemko 411APKL Full Mortise Automatic Door Bottom, Aluminum, PemkoPrene™ Insert, Low Closing Force

Pemko 411APKL Full Mortise Automatic Door Bottom, Aluminum, PemkoPrene™ Insert, Low Closing Force 

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 that contacts the jamb as the door is closing, forcing the drop-bar seal down against the floor/threshold.

• Especially over uneven surfaces, both PemkoPrene^® (PK) and nylon brush (NB) provide excellent seals to keep out draft, dust, moisture, insects, fumes, light, and sound.
• Can be mounted to either wood or hollow metal doors
• End plates are provided for all mounting applications
• Seals up to a 3/4" gap under the door 
• 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.
• All Pemko automatic door bottoms are provided NET length.
• Smoke Tested - UL1784 - tested in accordance with UL 1784-2001Air Leakage Tests of Door Assemblies, and meet the performance criteria for allowable air leakage as specified in NFPA 105-99 Installation of Smoke Control Door Assemblies. Meets the requirements for category H - Smoke Seals.
