Patton Archery - Bow Grip - Left Hand - Lot #12.  This grip is made out of Real Wood (Walnut). It is meant to mount on the Industry Standard (at the time) 21/32" wide riser. The actual ID measurement is .675". It's best to use a silicon type glue to mount on Risers. Don't be fazed by the screw holes on the inside of the Grip, they were used by the Manufacturer to hold the Grip while sanding and applying the finish (I provided a picture to show these screw holes). We used these grips on the Bows we manufactured at the time, P.I.C. Archery Bows. We closed our Archery Shop 16 years ago. We're now selling off the left-over inventory. Buyer pays UPS Ground Service Shipping.
