Leaving cored holes open during construction is not only and OSHA violation, but dangerous as well. Open cored holes are trip hazards. Debris, tools. or materials that fall through these holes can potentially injure workers below. The HOLE Solution is a fast, easy and inexpensive way to solve any of these problems. The HOLE Solution fits securely, stays solidly in place, and remains flush to the surface of the floor. A specially designed seal prevents water from passing through the hole and to the floor below. The HOLE Solution's bright OSHA yellow color provides visibility. Finally, Hole Solution covers are reusable. Replacement water seals are also available, but sold in package quantities only (2"-6" sizes sold 50/pkg: 7"-9" sold 25/pkg).
