Browning 1302520 V-belt Rule 60 in Oal 3V 5V

Product Description

The BROWNING 1302520 is a V-belt rule designed to help HVAC technicians, millwrights, and maintenance professionals accurately measure and identify V-belt sizes in the field. This 60-inch overall-length measuring tool is 3 inches wide and provides a fast, reliable method for determining correct belt length and cross-section without removing the belt from service. Built for repeated shop and field use, the 1302520 supports sizing work on 3V and 5V belt profiles, two of the most common V-belt cross-sections found in commercial HVAC drives, fan systems, and industrial equipment.

This belt rule is used wherever V-belts are installed, inspected, or replaced. Typical applications include rooftop HVAC units, air handling units, centrifugal fans, and industrial drive systems that run 3V or 5V narrow V-belts. Service technicians use it to confirm belt size before ordering a replacement, reducing the chance of a return trip or an incorrect part installation. It is equally useful in a service van, a mechanical room, or a shop bench setting.

Installation Notes

This is a measuring and sizing tool, not a mechanical component requiring installation. No power lockout is required for use, though standard safety practices apply when working near rotating equipment. Use the rule to identify belt size prior to ordering a replacement belt. Consult the equipment manufacturer specifications to confirm the correct replacement belt before installation.
