Forged Anchorage D-Bolt, 1/2 in or 5/8 in, 2-Pack
The Guardian forged D-bolt turns a bolted connection into a rated anchorage: a one-piece forged steel D-ring bolt that installs through a 1/2 in (00370) or 5/8 in (00371) hole and presents a permanent tie-off point wherever the structure accepts a bolt. Yellow finish keeps the rated point visible.
Each D-bolt serves one worker under OSHA 1926.502 and 1910.140, installed per the torque and substrate requirements in the manual. Sold as 2-packs to cover paired anchorage points.
Who Needs This Product
D-bolts are the fabricator answer to permanent anchorage: drill or use an existing hole, torque the forged bolt per the manual, and the structure carries a rated D-ring from then on. Steel platforms, equipment frames, and engineered connections all take them cleanly. Forged one-piece construction means no welded ring to inspect separately; the whole anchor is one grain of steel.
