Zero International 1675A Half Saddle Threshold – 5" Wide x 1/2" High Aluminum Mill Finish

The Zero International 1675A Half Saddle Threshold is a heavy-gauge aluminum threshold engineered for high-traffic commercial doorways and applications with extreme temperature differentials. Measuring 5" wide, 1/2" high, 36" long, and .250" thick, this half-saddle design is raised on one side to ease the transition at the door sill. Built to BHMA-certified standards and fire rated, it withstands direct drilling and screwing into concrete without the buckling or loose-screw issues common to lighter commercial materials.
