GapFix™ ADA & Fire-Rated Commercial Door Threshold - 5" x 1/2" x 168", Mill Finish Aluminum, UL Listed, ANSI/BHMA Certified, Made in USA (7 Day Production Time)

Barrier-Free 1/2" Saddle Threshold for Commercial & Fire-Rated Openings

The GapFix™ 5" x 1/2" x 168" Commercial Door Threshold in Mill Finish Aluminum is engineered for commercial openings requiring ADA accessibility, fire door compliance, and long-term durability.

With a 5" profile width, 1/2" ADA-compliant height, heavy-duty .109" wall thickness, and a 1000 lb load rating, this threshold is built for high-traffic commercial environments.

Made in USA and manufactured per order (7 Day Production Time).


Hole Configuration Options

Choose the configuration that best fits your installation requirements:

  • Pre-Punched Holes: Evenly spaced factory-punched mounting holes for fast, consistent installation.
  • No Pre-Punched Holes: Clean profile for field drilling, custom anchor placement, or architectural preference.

Pre-punched thresholds are ideal for standard installations. Non-punched thresholds are often specified when precise anchor spacing or concealed fastening layouts are required.


⚠ Built for Compliance - Not Commodity Imports

Many thresholds sold online are not certified for commercial ADA or fire-rated openings. The threshold directly affects door clearance, inspection approval, and long-term performance.

GapFix™ thresholds are engineered for commercial use and inspection-ready applications.
