Description: |
| This patent number is listed in a 1970 catalog from Greenlee Tool Co., for the Greenlee Nos. 676, 675 and 676 Positive Wire and Cable Grips, used for pulling cable through 2-inch and larger conduit. The key innovation is the use of cone-tipped set screws whose tips fit into countersunk holes. The stripped end of the wire to be pulled is held firmly in place by being pinched between the setscrew tips and those countersunk recesses. |
