Pemko 405 Residential Automatic Door Bottom, 36" Aluminum

The Pemko 405 is a spring-loaded automatic door bottom for residential wood or hollow metal doors. When the door closes, the sweep drops automatically to seal the gap at the threshold; when the door opens, it retracts. The 36" aluminum body can be cut down to a 24" minimum to match non-standard door widths. Profile dimensions are 5/16" wide x 2-1/2" high. Covered by a 5-year manufacturer warranty.

Key Features

  • Profile: 5/16" W x 2-1/2" H aluminum extrusion.
  • Door Compatibility: Wood or hollow metal doors.

Pemko 405CV36 – Frequently Asked Questions

1) How much space does the Pemko 405 door bottom need under the door?
The extrusion profile is 5/16 inch wide by 2-1/2 inch high, and it surface mounts to the face of the door with the sweep dropping below the door edge on close. Measure your gap at the threshold and your available face height on the door bottom rail against those two numbers before ordering.
2) Does the Pemko 405 work on a hollow metal door or only wood?
Both. The 405 is listed for wood or hollow metal doors, so the same part works on a wood entry slab and on a hollow metal utility or mechanical room door in a multi-family building.
3) Is the Pemko 405 automatic door bottom rated for a commercial opening?
The 405 is a residential-duty product. For apartment unit doors, houses, and light-traffic openings it is the right call; for a high-traffic commercial corridor or a fire-rated opening, specify a commercial-grade automatic door bottom instead, since duty rating and door assembly requirements are different in that application.
4) What is the difference between an automatic door bottom like the Pemko 405 and a regular door sweep?
A fixed sweep drags on the floor every time the door swings. The 405 is spring loaded: the sweep drops to seal at the threshold only when the door closes and retracts when it opens. That matters over carpet, thick tile, or a finished floor you don't want scuffed, and it keeps the seal from wearing flat. If the floor is bare and clearance is generous, a plain sweep is simpler and has nothing to fail.
5) Can I cut the Pemko 405 down myself on the job?
Yes. The 36 inch aluminum body is field cuttable to match a non-standard door width, with 24 inches as the floor. Cut from the end, keep the cut square so the sweep still tracks, and don't go under the 24 inch minimum.
6) Does the Pemko 405 need any adjustment after it is installed?
No manual adjustment. The sweep on the 405 deploys on close and retracts on open by spring action alone, so once it is mounted at the right height on the door face it operates on its own. That is the point of it on a rental or a fleet of units, where nobody is going back to tune a seal.
7) What finish does the Pemko 405 door bottom come in?
Clear anodized aluminum, and that is the only finish the 405 is built in. It reads as a plain silver-tone aluminum edge along the bottom of the door, which disappears against most metal door frames and stands out slightly against a dark stained wood slab.
