Pemko 171A36 Saddle Threshold Mill Finish Aluminum 36in

Product Description

The PEMKO 171A36 is a saddle-style door threshold extruded in mill finish aluminum. It spans 36 inches in length and provides a low-profile crossover surface at the base of a door opening, bridging the gap between the door bottom and the finished floor. The mill finish aluminum construction resists corrosion and holds up under repeated foot traffic in commercial and light industrial environments. Licensed contractors and door hardware installers use this threshold as part of a complete door perimeter sealing assembly or as a standalone floor-level transition piece.

This threshold is suited for standard 3-foot door openings in commercial, institutional, and residential applications. The saddle profile makes it appropriate for retrofit installations where an existing threshold needs replacement, or for new construction where a durable, code-appropriate floor transition is required. It installs at the sill of hinged door assemblies and is commonly paired with door bottoms or sweeps to improve weather resistance and reduce air infiltration at the sill line.

Key Features

• Saddle threshold profile provides a smooth, low-profile transition across the door sill
• Mill finish aluminum construction for corrosion resistance and long service life
• 36-inch length fits standard 3-foot door openings without field cutting
• Lightweight at 2.3 pounds, simplifying handling and installation
• Designed for use with door bottom or sweep assemblies to improve sill-line sealing

Compatibility

Designed as an OEM-style replacement or new-installation saddle threshold for standard 36-inch commercial and residential hinged door assemblies.

Installation Notes

Installation is typically performed by a door hardware installer or finish contractor using standard drill and screw fasteners at the door sill. The threshold should be test-fitted against the door bottom clearance before fastening to confirm proper contact. Ensure the subfloor or sill surface is clean, level, and dry prior to mounting. Follow local building code requirements for threshold height transitions, particularly in ADA-regulated or accessible-route applications.
