The Jamb Patch is compatible with masonry steel door frames from many major US manufacturers, including Steelcraft, ASSA Abloy, Dean Steel, Ceco, Curries, DCI, Republic, Pioneer, and Mesker. Review the product specifications for exact dimensions before purchasing.

The Jamb Patch does not carry a fire-rating label. Most frames susceptible to rust are in exterior openings, which typically do not require a fire rating. If your frame is fire rated, consult your local authority having jurisdiction (AHJ), such as the fire marshal, before proceeding.

The Jamb Patch has not been tested or certified to hurricane building code standards. If your location is subject to hurricane building codes, consult your local building inspector before installation to confirm compliance.

The Jamb Patch is manufactured from galvannealed steel, which is highly resistant to corrosion. When properly installed, it is designed to extend the life of the repaired portion of the frame for 10+ years under normal conditions.

No. The Jamb Patch can be installed by anyone with basic mechanical skills — no specialized door technician is required. Building maintenance staff, locksmiths, and painters are all suitable installers.
