Features

• Smoother action positive seal mechanism. All Pemko automatic door bottoms consist of an aluminum case that 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.
• This model is now available with nylon brush (NB) seals. The nylon filaments conform extremely well to irregular surfaces such as carpet, stone, and grout lines.
• Especially over uneven surfaces, nylon brush (NB) provide excellent seals to keep out drafts, dust, moisture, insects, fumes, light, and sound.
• 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.
• Pemko 411ANBL automatic door bottom by as much as 2 inches in the field. This trimming should only be done from the non-plunger side. Trimming from the plunger side can damage the automatic door bottom.
• The line includes models which can be mounted to either wood or hollow metal doors.
• End plates are provided for all mounting applications.
• All Pemko automatic door bottoms seal up to a 3/4" gap under the door except PDB-series, 420, and residential models which seal 1/2" maximum.
• Available in any size ranging from 24" to 72".
