Pemko's broad offering of products in the door bottoms category has been thoroughly tested, approved, and certified to help our customers meet today's air infiltration, smoke infiltration, sound infiltration, ANSI/BHMA standards, fire ratings and positive pressure fire door test criteria. Our line of nylon brush seals is second to none in the marketplace and new applications are being discovered continuously. During the past 5 decades, Pemko has introduced countless new products and innovations to existing products to our customers. Pemko is proud of its reputation as the leader in high quality innovative door seals and threshold products, including automatic door bottoms, door shoes, door bottom sweeps, door top weatherstrip and garage/overhead door weatherstripping.
Pemko offers a variety of automatic door bottoms for both residential and commercial applications. Automatic door bottoms are used to seal the space at the bottom of a door against infiltration from air, smoke, sound, dust, moisture, insects, fumes and light. The versatile Pemko automatic door bottoms conform to irregular surfaces. They are non-handed and reversible. Automatic door bottoms can be mounted to wood or hollow metal doors. Seals available: PemkoPrene™, Nylon Brush, Sponge Neoprene and Silicone.
Pemko's new low closing force automatic door bottoms feature a smoother action positive seal mechanism. All Pemko automatic door bottoms consist of an aluminum case which surrounds a movable drop bar seal. The drop-bar seal is actuated by a plunger which contacts the jamb as the door is closing, forcing the drop bar seal down against the floor/threshold. The simple yet practical engineering of the mechanism includes the following features:
- When the plunger contacts the jamb, the drop bar seal actuates from multiple compression points
- The plunger requires low "FeatherTouch" closing force to actuate the drop bar seal. The "L" at the end of all product numbers stands for low closing force. Pemko automatic door-bottoms meet pending closing force legislation and codes
- The drop bar seal actuates on the hinge side first
All models (except #420) include "tri-finned designed" seals which are offered in two materials: soft closed cell sponge neoprene (R) which remains pliable down to -70°F and PemkoPrene™ thermo-plastic elastomer (PK). The compressible PemkoPrene™ (PK) seal conforms well to the floor/threshold surface; the multi-point contact creates a superior seal. Most models are now available with nylon brush (NB) seals. The nylon filaments conform extremely well to irregular surfaces such as carpet, stone and grout lines. Especially over uneven surfaces, both PemkoPrene™ (PK) and nylon brush (NB) provide excellent seals to keep out draft, dust, moisture, insects, fumes, light, and sound.
- All medium duty models are also now available with sponge silicone (S) seals
- All models (except #430 and #412) are non-handed and reversible. Installation is fast and easy because disassembly is not required to change handing: simply flip the automatic door bottom, and you've reversed the hand. The clean symmetrical square-shaped case design also provides for even flush mounting
- The line includes models which can be mounted to either wood or hollow metal doors
- End plates are provided for all mounting applications
- All Pemko automatic door bottoms seal up to a 3/4" gap under the door except 420 and residential models which seal 1/2" maximum
- Available in any size ranging from 18" to 72"
- All Pemko automatic door bottoms are provided NET length
- All Pemko automatic door bottoms can be trimmed down by as much as 2" (stock lengths only). If non-stock sizes are ordered, order must note need to trim 2 inches from the size ordered
- The mechanism (all models) causes the drop bar seal to always actuate on the hinge side first. This feature prevents the seal from skidding or binding along the floor/threshold while the door is being closed
- When ordering, please specify if the automatic door bottom is for a semi-mortise application so that shorter screws can be provided
- Black nylon end plates are provided with all 4301 and 4131 models to protect the mechanism and to give a clean aesthetic appearance
- Plunger end plate prevents the plunger adjustment from rotating
- End plates keep debris out of the mechanism. Do not tighten with power tool
- Aluminum end plates are provided with all 434 and 411 models to protect the mechanism and to give a clean aesthetic appearance
- These models have all the same features as the 4301 and the 4131 except that these are handed, and disassembly of the mechanism is required to reverse the hand
- For easy non-handed installation, Pemko recommends using the 4301 rather than the 430, and the 4131 rather than the 412
- Aluminum end plates are provided with all 430 and 412 models to protect the mechanism and to give a clean aesthetic appearance
