Proper pinchweld preparation is essential for a successful replacement. Urethane companies today recommend that you leave 2 to 3 mm (between 1/16" and 3/32") of urethane on the pinchweld. This is easy to accomplish using a PrepMaster™. Put the chisel side up and use the heel of the blade to control the height at which the blade cuts the urethane (see drawing). One of the things we do here at Equalizer is to keep a list of things people ask us to produce. After we introduced the SuperScraper™ kit, we had a lot of technicians ask us to make a kit with a shorter handle. When asked what they would like to see in the kit, most of them mentioned a utility knife and an angled blade. We have taken all of those suggestions and incorporated them into this kit. The PrepMaster™ Kit has a lightweight aluminum shaft with a quick-change collet that lets you change the blade in seconds. The kit comes with one PrepMaster™, 5 of each size blade SC301 (1/2" wide), NY1246 (5/8" wide) and NZ1347 (3/4" wide) and TQ1438 (5/8" wide) angled blades. It also includes a utility knife with a quick-change feature, and a package of 5 utility knife blades. Made in Taiwan to our specifications.
