Electrical Box LB Assembly

The Taymac RLB350 is a rigid LB-type electrical box made from stamped steel. It provides a junction point for conduit runs requiring a directional change with a removable cover for wire access. This component is intended for electrical installations where durable metallic enclosures are specified.

Suited for Metallic Conduit Systems

Electricians and installers working with rigid or IMC conduit systems will find this box matches standard requirements for a 3-1/2 inch trade size. Projects that require non-metallic enclosures, smaller conduit diameters, or different hub configurations should look at alternative enclosure types.

3-1/2 Inch Trade Size Conduit Fit

The single specification that determines compatibility is the 3-1/2 inch trade size, which must match the conduit diameter used in the installation. Verify that the conduit system and wiring fill calculations align with this enclosure size before selecting this part.

Questions about this item

What conduit size does the 3-1/2 inch Taymac RLB350 rigid LB assembly accept?

The stamped steel body is machined for 3-1/2 inch rigid conduit, so the raceway you pull through must match that trade size.

Can I thread this LB onto existing galvanised rigid conduit already in the wall?

Yes, the female hubs cut to standard NPT threads, so it joins directly to any 3-1/2 inch rigid or IMC conduit without adapters.

How do I confirm the cover seals properly after I wire the Taymac RLB350?

Fasten the supplied cover screws evenly until the gasket compresses uniformly; a flat, gap-free seat around the perimeter shows the enclosure is rain-tight.
