Pemko 411ANBL36 Automatic Door Bottom - 36" Length Full Mortise Mill Finish Aluminum

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.
• 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 drafts, 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 PDB-series, 420, and residential models which seal 1/2" maximum.
• Available in any size ranging from 24" to 48".
• Leadline available upon request; consult Customer Service for options on profiles.
• 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-ups will not occur.
• All Pemko automatic door bottoms are provided NET length.
• This automatic door bottom is supplied with a Nylon Brush ("NB") insert - item number P516041.
• The standard color for this part is black, but it is also available in gray.
