This simple to use tool set allows you to extend the spring hinge barrel to hold it in the open position. The self-locking plier makes it easy to align the temple with the frame front and insert the hinge screw. Single handedly assemble those frustrating spring hinge frames in seconds.
For the ultimate in convenience use the Universal Nut and Screw Grabber (5070 and 5075) to easily insert the hinge screw into the barrel.
