These extenders work with hollow metal frames and wood frames. Check frame depth and configuration before ordering to ensure proper fit.

Measure the gap between door edge and frame stop. Order extender width that covers this gap plus overlap for proper coverage.

Standard mill aluminum finish is common. Some models may offer painted or anodized options. Verify finish availability for your specific width requirement.
