Window guides are also known as butterfly clips.oday there are probably twenty different rear window guides on the market, but you never seem to have the right one to replace the one you just destroyed. The window guide remover pliers were developed by an auto glass technician and designed to give you a better chance of saving the old window guide and assist you in putting it back on the new glass. The jaws are made so they fit around the window guide without damaging it, and exert pressure on the part that snaps together. The handle is made with a slotted area that can be used to pry the plastic snap loose so you can reuse the window guide. Made in USA.
