The key to the HitchClip Fall Arrest System is a 4.4-ounce anchoring clip that attaches to the roof framing with just four 16d (or equivalent) fasteners. Its compact size — 2 inches by 11 inches — means a worker can carry several in a toolbelt and install them as needed, says the maker. To make future roof access safer and easier, the low-profile clips can be overlapped with shingles and left in place after the job. Individual clips cost $10 each, compatible roof jacks $75 each.
