Tri-Arm and Quad-Arm Brackets

Tri-Arm BracketAvailable in three- or four-arm styles, our brackets are designed for the HVAC industry to facilitate accurate positioning of the shaft and blower wheel through its self-centering and self-aligning design. Arm lengths and strengths are customizable, such as 13-gauge for heavy duty loads, and provide additional rigidity to the blower side sheet where it is mounted. There are also five different bearing socket sizes offered. Tri- and quad-arm bearing brackets may be supplied preassembled by Triangle’s welding or mechanical fastening facility, or may be shipped knocked-down for customer welding.

At Triangle, we also provide a universal tri-arm in our repair kits. Engineered with multiple holes and extra-long arms, our universal bracket is an easy solution for standard repair needs.
