Tech Tip: Crack Expander

A Handy Tool for a Sticky Situation

Have you ever run across a stubborn crack where the resin just won’t flow? Maybe you’ve tried a variety of techniques like flexing the glass with a probe, and heating the glass, but still, the resin will not flow through the crack. What do you do? Don’t give up yet! You can use a handy tool called the 22425 Delta Kits Crack Expander.

The Crack Expander is designed to open cracks in glass, creating a wider path for windscreen repair resin to flow more freely throughout the break. To open a stubborn crack using the crack expander, make sure to retract the center screw until the rubber tip is flush with the bottom of the base. Moisten the cups with a drop of water or glass cleaner and place the crack expander on the inside of the windscreen with one cup on each side of the crack, making sure that the center screw is aligned with the crack. Press the suction cups firmly, but gently against the glass.

Once the crack expander is secure, turn the center screw clockwise until the tip touches the glass. Continue tightening until you see the crack begin to open up. Exercise caution when creating pressure on the glass. Glass is very volatile. While the design of the Crack Expander is to release from the glass if there is too much pressure, it is possible to make a crack run before the tool releases.

Once you have filled the crack with windscreen repair resin and have covered it with curing tape, slowly back out the center screw until it is no longer touching.
