Galvanized Iron and Steel Slip-On Framing and Fittings

To provide corrosion resistance in wet environments, this framing is galvanized. Slip the fittings over rails to construct custom railings, guard rails, storage racks, and shelving. Tighten the included set screws for a secure hold.

Galvanized iron fittings are malleable iron.
