Description

Dimensions: Casing measures .594" (W) x 1.844" (H). Length is custom cut to size up to 72". To determine size need see How to Measure for an Automatic Door Bottom.

Finishes: Available in choice of five anodized finishes.

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 environemntally 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. The seal lowers to fill gaps up to 3/4".

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 #4131

Mounting: This automatic door bottom can be surface mounted or semi-mortised applied to the face of the door. Select from options above which mounting option will be applied, since the two mounting options require different sized screws.

Handing: Casing is reversible and is compatible with both a right and left handed door.

InstallationInstallation instructions, end plates and screws provided. Screws are colored to coordinate with casing.

Compliance Details: Air Infiltration, Smoke, Sound and Fire Rated; UL Listed; BHMA Certified (see product data tab for more details)

Product Data

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!

Comments about Pemko #4131 Automatic Door Bottom, Aluminum with Choice of Seals, Narrow Casing:
Finally, a door bottom seal that really works. I had installed an extra high threshold a year or so ago (bought somewhere else). We had a problem with freezing cold air coming in from the garage as the door bottom had been cut unevenly. In no time at all the rubber gasket flattened out. This automatic door bottom solves the problem. It won't get stepped on and it was easily adjusted to make a very good seal.
Bottom Line Yes, I would recommend this to a friend

Comments about Pemko #4131 Automatic Door Bottom, Aluminum with Choice of Seals, Narrow Casing:
Durable, good materials - but the spring mechanism is a bit flimsy and does not work consistently. Needs re-engineering so that the actual seal consistently drops all the way across the door bottom.The mortised versions iare the best design, but mortising the door bottom is not for beginners. Putting the end caps on with the micro-screws is not for the feint or heart. I installed one of these about 10 years ago, and the upgrade to metal (not plastic) end caps is a plus. But the caps are thin and prone to bending out which can create problems hitting the door jamb, on the strike side.

Comments about Pemko #4131 Automatic Door Bottom, Aluminum with Choice of Seals, Narrow Casing:
There is an extra hole used during manufacturing but at least it should be plugged and rim finished properly. The web side does not shows this hole that damaged the units as a complete unfinished product.
