  • Unique patent-pending design creates uniform seal pressure across the entire door bottom resulting in superior acoustic performance. The seal drops parallel to the bottom of the door over its entire length creating a more even seal. 

  • 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.

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

  • Seals up to a 1/2" gap under the door.

  • Aluminum end plates are provided for each end of the door bottom to protect the mechanism and give a clean appearance. See additional images above.

  • This automatic door bottom is available in mill finish aluminum only.

  • 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.

  • See the Automatic Door Bottoms product category for more detailed information about these Pemko door bottoms.


  • Be sure to specify length in the Product Options area at top of page. If you are ordering a custom length, specify this length (in inches) in the CUSTOM LENGTH section.
  • Allow two to three weeks for shipment of 48" door bottoms. Shipment may be quicker, but we do not always stock 48" door bottoms.
  • This automatic door bottom (in stock lengths) may be trimmed down in length by as much as 2" on site.
  • Send us a message or call us at 800-260-5625 for pricing and lead time.
  • 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.
