This decorative surface mounted Automatic Door Bottom lowers a rubber seal when the door is closed for light and sound reduction as well as smoke and fire protection.
Seals: Available with a PemkoPrene™, Sponge EPDM and Sponge Silicone insert.
- EPDM is comparable to Sponge Neoprene, though has significantly better performance and is more environmentally friendly! It has great sound control properties and is resistant to solvents.
- PemkoPrene has a multi-point contact design and is great for uneven surfaces such as a tiled floor or carpet. Due to the way PemkoPrene™ is manufactured, it is not as firm as sponge silicone and allows for more leniencies.
- Sponge Silicone has great overall performance, except in the area of soundproofing. All three options remain effective in a wide range of temperatures and can be used on external doors.
Insert Replacement: This seal is designed to last through much usage, however if necessary a replacement seal can be purchased - see our Sponge Rubber Replacement for Pemko #412
Handing: This is supplied for Left Handed Doors. Handing can be reversed in the field, see installation guide. See How to Determine Handing / Swing of Door.
Installation: Installation instructions, screws and end plate included. Screws are colored to coordinate with casing.

How It Works
The high quality automatic mechanism consists of an aluminum case which surrounds a moveable drop-bar seal. The drop-bar seal is actuated by a plunger which contacts the door jamb as the door is closing, forcing the drop-bar seal down against the floor / threshold. The plunger requires low "Feather Touch" closing force to actuate the drop-bar seal. The plunger causes the seal to always actuate on the hinge side first, which prevents the seal from skidding along the floor/threshold while the door is being closed. Door hang-up will not occur!
