Telescoping Weld-Together Rails
Create posts of varying lengths. To telescope rails, slide one length of rail into the next larger size rail (for example, a 1 3/4" height rail fits into a 2" height rail and a 3/4" dia. rail fits into a 1" dia. rail). Weld the rails together at the desired length to create strong structures. These rails are not compatible with weld-together framing and fittings.
Carbon steel rails are lightly oiled.
Galvanized carbon steel rails have good corrosion resistance in wet environments and can be used outdoors.
Aluminum rails are about half the weight of steel and resist corrosion in wet environments.
304 stainless steel rails are more corrosion resistant than galvanized carbon steel. They also have good chemical resistance.

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.
Galvanized steel rails have good corrosion resistance in wet environments.
Steel rails are lightly oiled.
