|Tenth Frame finger inserts are dual ended. They have an oval at one end and a 1/4" forward power lift at the other. They are slightly softer than the coloured vise grips but not as soft as the super soft inserts. Available in Orange, Black and White. Outside diameter of 31/32" up to 13/16". Use 7/8 in a 31/32" hole for a 27/32" insert. 7/8" inserts and above are a 1" ouside diameter. Please note that these inserts are a little smaller than Vise so always order the next size up. So if you use 3/4 in Vise order 25/32 in Tenth Frame.
