Conduit Outlet Body for 1 1/4in Trade Size

This aluminum conduit outlet body accepts 1 1/4in threaded conduit in hazardous locations rated Class I Division 2 and Zone 2. The LB body style provides a 90-degree change of direction with a flat back for surface mounting. A 28.8 cu in interior capacity accommodates wire splices and pulls in industrial and commercial electrical installations.

Installation Notes and Common Issues

The threaded hubs accept IMC and RMC conduit directly without adapters. Installers must use the compatible OL-450 cover to maintain the hazardous-location rating. Powder-coated aluminum resists corrosion but requires care not to cross-thread the 1 1/4in connections during assembly. Ensure all threads are clean and properly engaged before tightening.

Pre-Order Compatibility Check

Verify that your conduit run uses 1 1/4in trade size IMC or RMC and that the installation environment falls within Class I Division 2 or Zone 2 hazardous location requirements. Confirm the 90-degree LB orientation matches your planned pull direction and that the flat-back mounting surface is suitable for the intended location.

Questions about this item

How can I verify the outlet body is correctly installed after setup?

Check that the powder-coated gray aluminum body sits flat against the mounting surface, the 1 1/4 in threaded hub aligns with your conduit, and the LB-style 90-degree bend routes cable smoothly without binding.

What comes in the box and what must I purchase separately?

The box contains the OLB-4 conduit outlet body with a 28.8 cu in capacity; the compatible OL-450 cover is sold separately and required to complete the enclosure.

Which version should I choose for a hazardous-location run with 1 1/4 in conduit?

Select the OLB-4 model — it is rated for Class I Division 2 and Zone 2 hazardous locations and matches 1 1/4 in IMC or RMC trade size.
