Elevate your billiard experience with Pro Cut Penguin Rails. Crafted for precision and durability, these rails ensure consistent ball response for enhanced gameplay. Designed to fit most standard table sizes, they offer a sleek and professional look. The pre-2001 93" Valley tables were made to make money fast. The original rails are cut at 43 1/2 degrees at the corners and have a whopping 4 5/8" - 4 3/4" opening that was designed to "swallow" the balls. And that's good if you own the bar. "Quicker games, more quarters". Except that it's not quite the challenge that say a Diamond table offers. Adding extra facings doesn't really do the job either. Here's what Penguin did: Corner pocket angles are now cut at 51 degrees (call it 141 if you want) Corner pocket opening is now 4 1/4" Cushion facings are now 3/16", 60 durometer neoprene (Standard facings are 70 duro SBR rubber) The rails are "thicker" creating a deeper 'shelf'. Premium Penguin Brand K55 - this is a proprietary formula for the perfect bounce. We do not use spray on contact cement like the competition. Each piece of rubber is sanded and attached with resin glue for the best no-void bond. Weight - These rails weigh just under 15 pounds per set. Compare that to a new Valley set at only 10 pounds. Our new PRO POCKET rail set is SO SOLID you will be amazed. The "thunk" is gone. Very quiet and so fast. A Ridge along the back of the rail - because some folks request this feature. These rails are not intended for the casual player. These rails are for the serious player who wants to sharpen his/her game
