The Concrete Edition Sink Hole Saver™ by Omni Cubed protects finished concrete countertops from breakage during lifting, transport and installation. This new model accommodates very thick countertops with edge thicknesses of 1.25 inches through 2.5 inches. The product features mechanical clamps which stay secure, and the easy-grasp clamp knobs are effortless and quick to tighten. The stiffening rail is very strong, yet light-weight, and features a convenient sliding channel for custom placement of each clamp. In addition, sink hole savers can be applied in the shop and left on the countertop all the way to and through the install. Available in 4, 6 and 8 feet lengths; make sure to specify “concrete edition” when ordering this model.
