Pemko 411APKL Full Mortise Automatic Door Bottom, Mill Finish Aluminum

Pemko 411APKL Full Mortise Automatic Door Bottom, Mill Finish Aluminum

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.
