3M AN112A Protecta Pro Threaded Eyebolt Anchor

Product Description

The 3M AN112A is a compact, threaded steel eyebolt anchor designed to provide a fixed fall arrest anchor point when bolted directly to a structural surface. Measuring 3.6 inches by 0.5 inches by 3.6 inches and weighing 0.85 pounds, this single-piece anchor integrates a 1/2-inch by 1-3/8-inch mounting bolt and a formed steel eye into one low-profile assembly. The integral eye eliminates the need for a separate tie-off ring, keeping the connection point tight to the structure. It is installed by safety professionals, contractors, and trade workers performing work-at-height tasks on construction sites, industrial facilities, and commercial rooftops.

The AN112A is intended for applications where a permanent or semi-permanent overhead or structural fall arrest anchor point is required. Its compact footprint suits installations in confined or close-clearance areas where a larger anchor plate would be impractical. The threaded mounting bolt fastens directly into a structural member, making it appropriate for steel, heavy timber, and similar load-rated substrates when used within the substrate's rated capacity. A single worker connects a personal fall arrest system directly to the integral eye.

Key Features

• Compact 3.6 x 0.5 x 3.6-inch profile suits tight or confined anchor locations
• Integral 1/2-inch by 1-3/8-inch threaded mounting bolt included — no separate hardware required
• Formed integral eye provides a direct, low-profile tie-off connection point
• Steel construction for durability in demanding job site environments
• Lightweight at 0.85 pounds for easy positioning during installation

Compatibility

Designed as a fall arrest anchor point compatible with standard personal fall arrest systems using compatible connectors attached to the integral eye. Verify that the structural substrate meets the minimum anchor strength requirements specified by OSHA and ANSI Z359 standards before installation.

Installation Notes

Installation must be performed by a qualified person familiar with fall protection requirements under OSHA 29 CFR 1926 Subpart M and ANSI Z359 standards. Before installing, confirm that the mounting substrate is structurally adequate to support the required fall arrest loads. Thread the integral bolt into the structural member to the manufacturer-specified engagement depth and verify secure seating before connecting any personal fall arrest equipment. Never use this anchor on a substrate that has not been evaluated for the rated anchor load.
