Understanding Three-Bend Saddles

What is a three-bend saddle?

A three-bend saddle is a type of conduit bending where there is a center bend with two side bends. The most common configuration for a three-bend saddle includes a 45-degree bend in the center and two 22.5-degree bends on either side. The center bend usually has twice the angle of the side bends.

To create a three-bend saddle, you need to add the total shrinking amount and distance measurement for the conduit. This will help determine where to place the center bend along the conduit. The measurement for the center line is crucial for achieving the correct angles for the bends.

What is the definition of bend length?

Bend length refers to the increase in length of a steel bar when it is bent. When a steel bar is bent, there is stretching in the bending area which causes the length to increase slightly. The degree of bend and the grade of steel used will influence the amount of length expansion.

As the bending degree increases, the length of the steel bar will also increase. Conversely, if a higher grade of steel is used, the length expansion will decrease. It is important to consider these factors when bending conduit to ensure accurate measurements and bends.
