Pemko Automatic Door Bottom #411 - Full Mortise

Suitable for wooden doors, this full-mortise door bottom requires a 9/16" wide by 1-3/8" deep mortise in the bottom edge of the door.

Select 32" or 36" length. May be trimmed down in length by as much as 2" without interfering with drop-bar mechanism.

Non-handed and reversible. Disassembly is not required to change handing. Simply flip the door bottom and you have reversed the hand.

Aluminum end plates are provided for each end of the door bottom to protect the mechanism and give a clean appearance. See drawing at bottom of page.

Three types of seal are available for this door bottom. All are designed to conform well to the floor/threshold surface. See additional photos at bottom of page.

PemkoPrene (PK). Pemko's proprietary thermo-plastic elastomer, which has a hollow cross-section and is very compressible.
Soft, closed-cell sponge neoprene (R). Remains pliable down to -70 degrees F.
Sponge silicone (S). Pemko's newest and most expensive option.

This product has been acoustically tested and given a "Sound Transmission Class" (STC) rating. See the HARDWARE INFO link on the left side of this web page for more technical information from Pemko.

NOTE: We recommend that these automatic door bottoms be installed by a carpenter or contractor or other person with experience hanging doors. Installation may involve rehanging the door and cutting it to height. For the full-mortise styles, it also involves cutting a deep mortise in the bottom edge of the door with a router. Pemko does provide installation instructions.
