Pemko is a quality North American hardware brand with a 65-year history of providing excellent products and services. Starting with their original facility in Ventura, California, they quickly expanded into strategic markets until they were able to service all of North America from additional facilities in Toronto, Canada, Vancouver, Canada, and Memphis, Tennessee.

They specialize in products for thresholds, gaskets, glazing equipment, weatherization equipment, molding, door hardware, hospitality construction, and much more. In recent years they have even expanded into the green products industry and into Astragals & Meeting Stiles, Brush Gasketing, Door Bottoms, Adhesive Gasketing, Fire Glazing, Floor Molding, Trim & Handyshapes, Hinges, Perimeter Gasketing, Modular Ramps, Residential Thresholds, Sills for Pre-Hanging, Commercial Thresholds, Weatherization products, Sliding & Hanging Door Hardwares, Lites & Louvers, Door & Frame accessories, and Hospitality products.

Surface and Semi-Mortise

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.

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 models 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 PDB-series, 420, and residential models which seal 1/2” maximum.

Available in any size ranging from 18" to 48".

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.

Lead line available upon request; consult Customer Service for options on profiles.

The drop-bar seal actuation mechanism (all models) causes the drop-bar seal to always actuate on the hinge side first. This feature prevents the seal from skidding along the floor / threshold while the door is being closed. Door hang up will not occur.

This automatic door bottom is supplied with a Nylon Brush ("NB") insert - item number P516041. Standard color for this part is black, but it is also available in gray.
