Pemko 411ANBL Full Mortise Auto Door Bottom, Nylon Brush Insert

Pemko 411ANBL Full Mortise Auto Door Bottom, Nylon Brush Insert provides a reliable solution to seal gaps under doors, keeping out drafts, dust, moisture, insects, light, and sound. This automatic door bottom lowers a durable drop-bar seal as the door closes, ensuring a tight fit on floors while maintaining smooth operation.

The aluminum full-mortise case houses a nylon brush insert that conforms to irregular surfaces such as carpet, stone, or grout lines, providing a flexible seal in any environment. Moreover, the drop-bar mechanism ensures hinge-side actuation, preventing seal skidding and door hang-up during closure.
