Pool Table Rail Cushion Profile Type – How To Choose

Which Pool Table Rail Cushion Profile Should I Purchase?

Which Pool Table Rail Cushion Profile Should I Purchase?

How do I choose the correct pool table rail cushion is a question we get asked all the time. You must first determine the size of your pool table. Once you know your pool table size, you can determine the profile shape of your pool table rubber cushions.

K66 Profile Pool Table Rail Cushions

The industry standard and BCA approved cushion is a full profile K-66 cushion. K-66 refers to the shape of the cushion. Full profile means that it is a full size cushion. K66 rail cushions are the most common rail cushions used today. It is the standard rail cushion we send out in all of our complete pool table refelting kits.

K55 Profile Pool Table Rail Cushions

The K-55 profile rail cushion is used mostly in commercial coin operated pool tables, although most of the rubber cushion profile shapes have been used on commercial pool tables at one time or another. The K-55 cushion has the same general profile shape of the K-66 cushions but is larger in size.

U23 Profile Pool Table Rail Cushions

The U-23 profile cushions are not as widely used and are a smaller profile than the K-66 cushion and were used on some lower priced pool tables.

When choosing a pool table rubber cushion you want to make sure it is made out of pure gum rubber. It should also have canvas cloth reinforcement on both the top and back sides of the cushion. The canvas on the top of the cushion helps maintain its shape and controls the action of the rubber. This provides more accurate and consistent game play. The canvas on the back side of the rubber helps maintain shape. It also allows the rubber cushion to bond tightly to the wood rail ensuring that it will not separate and come loose.

Making sure you have the correct rail rubber cushion profile ensures that the cushion height or the rail strike point is in the proper position in relation to the ball. The rail height or strike point should be 63 1/2% of the ball diameter. (ex. standard pool ball is 2 1/4″ in diameter, rail height should be .635 x 2.25 or 1.43″ in height.)
