These dividers are designed for the scribing needs of sheet vinyl installers. The rounded body fits comfortably in the users hand. Includes a bent leg and a removable straight leg that can span up to six inches. Legs are adjusted using the folding thumbscrew. The bent leg offsets the tool from the wall for easier wall scribing. The straight leg can be removed and used for pencil scribing using the knurled steel thumb nut. Both legs have knurled steel caps to hold replacement needles (No. 129).
