Interlocking J Hook Strip for Thresholds — Bronze

This solid-bronze interlocking threshold hook strip, also called a J-hook, fastens to the bottom of a wood door or casement window sash. It interlocks with the threshold—also called a saddle—to seal against air, light, insects and pests.

As the old-timers say, “Nothing beats interlock.” Properly fitted, the hook strip completes the traditional interlocking threshold or saddle system with a durable metal-to-metal seal.

Installing J-Hook on Doors and Casement Windows

Fasten the hook strip to the bottom of the door or casement sash with staples or ring-shank nails so it engages the interlocking threshold or saddle evenly across the opening. Accurate clearance and careful fitting are essential. To trim the material yourself, use tin snips.
