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.

Rails have bolt holes on all sides. Connect multiple rails with brackets and connectors.
Anodized aluminum rails resist wear and corrosion better than unfinished aluminum rails.
Telescoping rails fit together by sliding one rail into the next larger size. Secure them with a locking pin (sold separately).
