Pemko 158A36 Offset Saddle Threshold Aluminum 36 Inches

Product Description

The PEMKO 158A36 is a commercial-grade offset saddle threshold made from mill finish aluminum. It bridges the gap between door and floor, providing a smooth transition surface that reduces trip hazards while sealing the base of the door frame against air, water, and debris infiltration. At 36.5 inches in length, 5.5 inches in width, and 0.5 inches in height, this threshold is sized for standard 36-inch door openings. It weighs 2.7 pounds, making it straightforward to handle and position during installation. Contractors, door hardware specialists, and commercial finish carpenters install this component as part of a complete door assembly on new construction and retrofit projects.

The 158A36 is suited for interior and exterior commercial and residential door openings where a low-profile offset saddle profile is required. The mill finish aluminum construction performs well in high-traffic corridors, entry vestibules, and tenant separation doorways. Its offset saddle design accommodates slight floor height differences between adjacent surfaces, a common condition in renovation work and multi-floor commercial buildings. PEMKO thresholds are part of a broad architectural door accessory line that includes fire and smoke-rated assemblies, giving specifiers flexibility across building types and occupancy classifications.

Installation Notes

Threshold installation is typically performed by a door hardware specialist, commercial carpenter, or licensed contractor. Before installation, ensure the door is in the closed and latched position to verify proper clearance and fit against the threshold profile. Fasten the threshold to the floor substrate using fasteners appropriate for the floor material, following local building code requirements. Verify compliance with applicable ADA and IBC threshold height and slope requirements before finalizing the installation.
