Our design is hefty and solid, with deep serrations to get a good bite on one side, and little bumps on the other where the "Z" clicks together for more secure fit. Stock size is 2" long by 1 7/8" high giving 1 1/4" grip surface to wall and 5/32" inside grip. Countersunk holes.
Sold as a set (includes 2 pieces per set).
Note: Any custom length available. Call for pricing.
