Zero 367AA Heavy-Duty Surface Mounted Automatic Door Bottom

The Zero 367AA is a heavy-duty, surface-mounted automatic door bottom engineered for commercial door assemblies where air, smoke, sound, and flame infiltration must be controlled. Zero's patented automatic mechanism drops a concealed flat spring-actuated seal the moment the door closes — compressing the adjustable plunger against the door frame — and retracts it fully on opening so the seal never drags across the floor during normal traffic.

Features & Specifications

  • Surface-mounted installation — no mortising required
  • Anodized aluminum (AA) body construction for corrosion resistance and long service life
  • Supplied with closed-cell sponge neoprene seal for effective compression against floor or saddle
  • Patented automatic drop mechanism activated by adjustable plunger at door frame contact
  • Seals against air infiltration, smoke, sound transmission, and flame penetration
  • Fire Rated: UL10C (positive pressure)
  • ANSI/BHMA Listed: 367AA, 367BK, 367D, 367G — R3B3341
  • Available lengths: 16", 36", 38", 42"

Application Notes

Designed for commercial interior and exterior doors in applications requiring fire, smoke, or acoustic door bottom sealing — including office buildings, multi-family residential, healthcare, hospitality, and institutional facilities. Confirm door thickness and undercut clearance before ordering. Surface-mount profile is compatible with most standard commercial door stiles.
