Flat and L-Shaped Bolt-Together Framing and Fittings

Rails are drilled with consistently spaced holes for multiple mounting options that do not require machining. Use this bolt-together framing to build guards, tables, and racks.

Galvanized Steel L-Shaped

Zinc-Plated Steel and 304 Stainless Steel L-Shaped

Powder-Coated Steel L-Shaped

Zinc-plated steel rails are more corrosion resistant in wet environments than powder-coated steel.

Galvanized steel rails have better corrosion resistance in wet environments than zinc-plated steel and can be used outdoors.

Steel Bolt-Together Framing and Fittings

Rails are drilled with consistently spaced holes for multiple mounting options that do not require machining. Use this bolt-together framing to build guards, tables, and racks.

For technical drawings and 3-D models, click on a part number.

Rails

Rails have bolt holes on all four sides. Connect multiple rails with brackets or slide one length of rail into the next larger size and bolt together using curved-bolt or locking-pin connectors. Select connectors based on the larger size rail in the connection.

Galvanized steel rails have good corrosion resistance in wet environments.

Steel rails are lightly oiled.
