This Quad 4-in-1 Grips combines four different inserts in one. It's a clever combination of four popular styles (Perfect Oval, Power Oval, Perfect Oval Mesh, Round Mesh), the Quad 4-N-1 insert is the one insert that works four ways.The Quad also comes with a great feature, the patented "Glue Groove", a small channel encircling each insert that's designed to prevent excess adhesive from reaching the surface of the bowling ball.
