Pemko 411ARL 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 which contacts the jamb as the door is closing, forcing the drop-bar seal down against the floor / threshold.
- The nylon filaments conform extremely well to irregular surfaces such as carpet, stone and grout lines.
- 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.
