3M™ Protecta® 2104703 Reusable Sliding I-Beam Anchor

Smooth Horizontal Mobility. Dual Ratcheting Alignment. Zero Metal-on-Metal Wearing.

The 3M Protecta Sliding Beam Anchor (2104703) introduces smooth trailing maneuverability, fast tool-free adjustments, and rugged fall arrest security to large commercial framing arrays and industrial steel builds. Engineered to remove the primary workflow bottleneck of traditional stationary anchor points—which force workers to repeatedly disconnect and re-attach as they move along a structure—this heavy-duty mobile beam anchor slides behind the user. It provides ironworkers, bridge contractors, warehousing technicians, and utility crews with a portable tie-off station optimized to follow self-retracting lifelines (SRLs) and safety lanyards along overhead I-beam frameworks.

High-tensile structural durability and smart hardware safety serve as the bedrock of this premium Protecta® anchorage connector. Manufactured from a combination of zinc-plated steel and robust aluminum, the frame features a centered D-ring anchor point that evenly balances fall arrest forces up to a 5,000 lb (22 kN) minimum tensile strength. It incorporates a highly versatile jaw system that adjusts to fit beam flanges from 3.5 to 14 inches wide and up to 1-1/4 inches thick using built-in, easy-press adjustment buttons. The system features a guarded locking mechanism on the lower chassis to prevent accidental disengagement from building debris, while replaceable snaped-in wear pads eliminate grinding metal-to-metal contact to preserve both the tool and your structural beams.

Why the 3M Protecta 2104703 Sliding Anchor Rules the Steel:

• Continuous Hands-Free Trailing: Trailing design moves smoothly along overhead beams behind the worker, keeping hands free for tools and tasks.
• Versatile 3.5" to 14" Flange Fitment: Quickly adjusts to fit a variety of standard building beam dimensions across changing worksites.
• Integrated Dual Ratcheting Jaws: Responsive dual-button slider setup allows for secure alignment on the flange without requiring additional hand tools.
• Replaceable Protective Wear Pads: Removable buffer pads eliminate raw friction damage on steel beams while extending the service life of the anchor.
• Guarded Safety Lock: Low-profile lock placement prevents accidental opening if the underside strikes structural obstructions.
