Back to the basics - a maple wood block fabricated to test the height of the rail cushion for billiard tables that use 2 1/4" standard balls. Gauge is between 1 13/32" and 1 7/16" to ensure rubber cushions are mounted correctly on the wood rail. 

Is your rubber positioned correctly for the best bounce possible on your pool table rail? Find out with our Rail Height Gauge. 

The tolerance allowed is marked on the block for easy reference.
