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 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.
Zinc-plated steel rails resist corrosion better in wet environments than plain steel rails.
Galvanized steel rails resist corrosion better in wet environments than zinc-plated steel rails.
Steel rails are lightly oiled.

Surface brackets connect rails. These brackets do not have mounting holes already drilled, so you can drill holes where you need them or weld the brackets in place.
Zinc-plated steel brackets are more corrosion resistant in wet environments than powder-coated steel brackets.
Galvanized steel brackets have better corrosion resistance in wet environments than zinc-plated steel brackets, and they can be used outdoors.
Aluminum brackets are half the weight of steel brackets, and they resist corrosion in wet environments.
304 stainless steel brackets are more corrosion resistant than galvanized steel brackets. They also have good chemical resistance.
