Interlocking Threshold 4-1/2" Wide x 15/16" Tall

Made of solid Architectural Bronze (brass alloy), this interlocking threshold is the gold standard for sealing a door. When the door closes, the hook engages into the threshold’s groove, “interlocking” the door and threshold together. The result is a snug, reliable barrier that blocks drafts, rain, dust, and even light.

This heavy-duty threshold is a long-term investment in comfort, energy efficiency, and durability—ideal for both restorations and new construction projects.
