GapFix™ Slip Resistant ADA & Fire-Rated Commercial Door Threshold - 5" x 1/2" x 24", Mill Finish Aluminum, UL Listed, ANSI/BHMA Certified, Made in USA (7 Day Production Time)

Barrier-Free 1/2" Saddle Threshold with Permanently Embedded Slip Resistant Surface

The GapFix™ 5" x 1/2" x 24" Slip Resistant Commercial Door Threshold in Mill Finish Aluminum is engineered for commercial openings requiring ADA accessibility, fire door compliance, and enhanced slip resistance in wet or high-traffic environments.

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

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

Permanent Slip Resistant Technology

Unlike surface-applied coatings that peel, chip, or wear away, the GapFix™ slip resistant surface is embedded directly into the aluminum.

• Nickel and titanium particles are embedded and fused into the threshold surface
• Originally developed for high-demand industrial environments
• Provides long-term slip resistance in wet conditions
• Will not flake or wear off under normal commercial traffic
• Surface texture comparable to high-grit sandpaper

Ideal for schools, hospitals, retail entrances, grocery stores, industrial facilities, and any opening exposed to rain, snow, or moisture.

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.
