IMC 90° Elbow

Elbows

The IMC 90° elbow turns an IMC steel conduit run through a right angle, making it easy to go around building corners or switch between vertical and horizontal runs without bending conduit on site.

IMC 90° Elbow

Available from 1/2 in. to 4 in. for 90-degree IMC conduit turns at wall corners or in tight spaces. The strong, durable elbow keeps runs neat, simplifies installation and improves the safety of the wire protection system.

IMC 90° Elbow Features

Changes the direction of IMC conduit runs by 90 degrees.
Designed for IMC conduit of the same size; the connection method depends on the elbow end type and fittings.
Made of strong, durable metal for electrical installations that need robustness.
Makes runs around wall corners, ceilings or tight spaces easy and neat.
Removes on-site conduit bending for faster installation.
Protects the wires inside and lets the run change direction to suit the installation area.
Suited to outdoor electrical runs and areas where conduit needs a 90-degree (right-angle) change of direction.
Standards: TIS 770-2567

How to Use

Choose an IMC 90° elbow that matches the IMC conduit size in use.
Measure and plan the conduit route to suit the site before installing.
Connect the elbow to the IMC conduit using fittings suited to the model.
Fix the conduit to walls, ceilings or the building structure with suitable clamps or supports.
Before pulling wires, check the run and the inside of the elbow for sharp edges that could damage insulation.
