Double (Two) Groove Fixed Bore A/B Pulley
 2BK Sheaves

This pulley will fit "A" or "B" size belts
"A" will ride further down in the groove, so determine diameter by PD required

2BK Sheaves are precision machined from gray cast iron, statically balanced and epoxy powder coated.

Comparable Pulleys to Browning, Maska, Woods, Congress and many other brands

The "PD" Pitch Diameter indicates the outer diameter where the belt rides in the groove.
Example: "A" belt size will sit lower in the groove, leading to a smaller diameter than the real outer diameter.
