Recovering pool tables can indeed be a challenging task due to the variations in table designs. One aspect that can be particularly confusing is selecting the appropriate rail cushions, as they are available in different profile shapes. Choosing the correct rail cushions is crucial to ensure that the balls strike the rail at the proper point, typically at a height of 1.43 inches.
 
In general, the K66 profile is commonly used for home and commercial 3-piece slate tables. K55 rails are often found on carom tables and most coin-operated tables, while U23 rails are used for certain home and commercial tables as well. To determine the exact rail cushions your table requires, you can measure the back side of the cushion where it is attached to the table (referred to as the "Dimensional Height"). Additionally, measuring the top side of the rail (known as the "Angle Width") is recommended.
 
By comparing these measurements to the rail profile dimensions, you can identify the suitable set of cushions for your table. It is important to note that the set of six table cushions you mentioned features a U23 profile, which is specifically designed for tables that require this particular rail profile. This set includes enough cushion material to complete a standard 8-foot pool table.
 
During the recovery process, ensure that the cushion is properly adhered to the rail with the notched side against the rail. The top canvas part of the cushion should face upwards from the table's surface. This installation orientation helps the cloth fit snugly when covering the entire rail, resulting in optimal performance.
 
Always measure accurately and consult professionals or experts if needed to ensure the proper selection and installation of rail cushions for your specific table.
