Barwalt Tile Wedges * All of our wedges have a gripper built into the design which makes removal easier. Wedges are a great tool for leveling the first row of tile on a tub or straightening rows as they stack up as a wall. We have three different sizes for all your needs. Our Super Wedge handles the jobs where the joints are larger and the Gripper Wedge, which has less incline and is narrower, will get into those tight spots. If the Gripper Wedge bottoms out before opening the joint wide enough, just snip off the end and the wedge will be larger.
