Product Overview

Zero 350AA Automatic Door Bottom, Regular Duty, Aluminum Clear Anodized


The patented automatic door bottom technology from Zero ensures an efficient seal against the floor or saddle. As the door is closed, the adjustable plunger is compressed against the door frame, activating a concealed flat spring mechanism. Zero door bottoms are designed to block penetration by air, sound, smoke, and flames.
