Pemko 252X3AFG36 36" 3' x 5-1/8" x 1/2" Thermal Barrier Saddle with Frost Guard Mill Finish Aluminum Finish

The 252X3AFG36 thermal barrier saddle threshold eliminates tripping hazards where floor heights differ by 1/2". Installed at doorways and room transitions, this half threshold creates a smooth surface transition while addressing thermal bridging concerns. The frost guard feature prevents ice buildup in cold climates. Pemko engineers this 36-inch threshold from anodized aluminum with mill finish for durability in high-traffic commercial applications.

This ADA-compliant threshold measures 2 inches wide and handles floor offsets precisely. The thermal barrier design reduces heat transfer through the threshold assembly. Mounting hardware comes included for straightforward installation over existing subfloor conditions.
