V-Groove wheels are constructed from grey iron castings. The 90 degree grooves, machined into the face of the wheels, direct the load to each face of the angle track. Can also be used on a flat surface. Ideal for heavy loads. Look for 7/8" or 1-3/8" wide grooves. The groove depth is half of the width.
