Crain - Rolling Hand Groover No. 973

The precision guide wheels of the wall chaser follow the joint to cut a groove for heat sealing. The groove starts in the middle of the joint with the front blade, then moves toward the wall with the rear blade. Groove curves and circles using a snap-on foot plate that allows the rear end to slide. The blade depth is adjustable. Debris flows out under the handle, which opens for cleaning. All adjustments are made using a 1/8" hex key (included) that stores on the tool. Accepts standard blades and comes with two 4 mm #974 blades. Includes a protective bag.
