Installing a ceiling hook in a garage or shop and the joist is 4-3/8 inches below your drywall — a 5-inch hook is too long and bottoms out before the threads engage properly. You need the right reach for the actual cavity depth. This 4-3/8-inch ceiling hook is the correct match for shallower ceiling cavities where a longer hook would bottom out before getting proper thread engagement in the joist. Accepts a matching lag eye bolt for direct wood fastening into structural ceiling framing. Zinc-plated steel handles garage and shop moisture exposure without rusting through the first season. Standard on garage builds and shop ceiling installs across Knox County NE and Plymouth County IA — the right-reach ceiling hook that installs properly the first time because it fits the actual ceiling depth Stocked at Crofton Lumber and Akron Lumber.
