Most models are 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, both PemkoPrene® (PK) and nylon brush (NB) provide excellent seals to keep out draft, dust, moisture, insects, fumes, light, and sound.
All models are 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.
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 420, and residential models which seal 1/2” maximum.
This automatic door bottom is supplied with a Nylon Brush (“NB”) insert – item number P516041.
