These are a welcome relief when you are replacing a windshield. When you need to cut out a windshield, use these NeckSavers™ from Equalizer® after you cut out the sides and top of the glass. Simply slide in these durable, plastic spacers, and they will help save you from having to push out on the glass with your neck or body. The NeckSavers will roll down the post and keep the glass elevated. As more of the urethane is cut you just put a small amount of upward pressure on the glass (with your hand) and the NeckSavers holds the glass up. These come in sets of 2. Made in USA. Buy a pair from AEGIS® Tools today and save your neck to hold up your head.
