General description Spring band clamp locking tool set allows the technician to keep spring type fuel or coolant hose clips open while working without having a bulky set of pliers in the way. This set includes three sizes of spring clip holding tools designed to hold open spring type clips found on fuel lines, vacuum, and coolant pipes. Technical specifications Sizes: 4mm, 9mm & 12mm apertures Usage Open the spring clip with pliers. Slide the appropriate holding tool into place. Remove pliers; the clip stays open, leaving the mechanic's hands free to work. With the clip holding tool in place, the clip can easily be positioned by hand without fear of trapped fingers. Other information Eyelet doubles as a handle and a place to tie a ribbon, string, or tie wrap to make finding the tool easier if dropped.
