Click here for our Quick Ship TMH Mortised Automatic Door Bottom. Stock size -  36" length is available to ship within 1 business day!

Dimensions: Body measures .562" W x 1.375" H. Extended flanges on both sides measure .42". Total width is 1.26". Length is custom cut to size up to 48". To determine size needed, see How to Measure for an Automatic Door Bottom.

Door Thickness: Model is compatible with 1-3/4" and 1-3/8" thick doors. However, different end plates are required for each door. Please select from options above.

Finishes: Available in aluminum mill finish.

SealsFitted with either a PemkoPrene or EPDM or Sponge Silicone seal. The seal drops to fill gaps up to .75". When choosing a seal it is essential to determine the purpose for sealing and the floor surface beneath the seal.

Sponge EPDM is comparable to Sponge Neoprene, but is made of a more Eco-friendly material and has overall superior performace. Specifically, it has great sound control properties. PemkoPrene™ is great for uneven surfaces such as a tiled floor or carpet (Nylon Brush Seal is a great option in this aspect, too). Due to way PemkoPrene 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 #411

How Automatic Door Bottoms Work

The Automatic Door Bottom utilizes a concealed flat spring mechanism which is activated upon opening and closing of the door. A brass plunger is compressed when the door is closed to automatically drop the seal, starting from the hinge side first. The seal is raised when the door opens. This motion ensures a smooth drop without a drag, even on an uneven surface. It is compatible with a door saddle or against the floor. The door bottom is built from durable materials that are meant to last. It has been tested through 5 million cycles!

Comments about Pemko #411 Automatic Door Bottom, Mortised Narrow Casing with Rubber Seals - .75" Drop:
I used it on an exterior door that couldn't use a threshold with a bulb. It worked well. The only problem was routing out bottom of door and the fact it was factory cut and i didn't receive the finish plates and screws.

Comments about Pemko #411 Automatic Door Bottom, Mortised Narrow Casing with Rubber Seals - .75" Drop:
This is for the Door to the Media Room and didn't want an ugly door sweep dragging across the floor and this mechanical sweep fit the bill perfectly to block the light and sound from exiting the room. The only con is the installation instructions were vague, 2 metal plates are included: one is a strike plate for the jamb and the other?? I had to guess, it went on the hinge side of the door covering the end of the sweep.

Comments about Pemko #411 Automatic Door Bottom, Mortised Narrow Casing with Rubber Seals - .75" Drop:
I'm the Condo President of a 1982 vintage building. The doors originally used a self sealing design and after 40 years of use, most had worn out and been replaced with very inadequate seals available from the big-box stores. I found TM Hardware on-line with perfect replacements for our original door seals. I did an initial set of 24 doors and the results were superb. We've now done almost half of the 200-plus doors in the building. Great noise sealing and draft sealing and everyone likes the way the seal lifts up when the door opens so that it doesn't drag on the wood floors. The design is from ASSA, a Swedish manufacturer of very high end door hardware, and it shows.
