Turbo 2-N-1 Grips Formula Xcel Round Thumb Insert 

Description

Unlike the smooth, quick release of Urethane thumb products, Xcel thumb products offer a more textured feel for slower release. They are made from softer, more pliable blend of material that makes them easy to drill, cut, bevel and sand without the use of a router or plug cutter. This product is often recommended for bowlers with very dry skin.Outside Diameters: Sizes 51/64 – 61/64 use 1 1/8″ Hole Sizes 31/32 – 1 1/16 use 1 1/4″ Hole
