DBI SALA 2100090 Perimeter Limiter Leading Edge Anchor, freestanding tie-off point for two users.
The Perimeter Limiter’s design makes the anchor provides an overhead anchor for up to two users that minimizes fall distances while reducing swing falls. Once craned into position on the deck, the Perimeter Limiter is pushed to a location and is ready to use. When it comes time to relocate the anchor to another area, it can be maneuvered in two ways. The Perimeter Limiter’s mast and anchorage arm can rotate around the counterweights making relocation to another close by area fast. If the anchor has to move across the deck to an area further away, the foam filled trailer tires and up front push bars make this easy..
Meets or Exceeds OSHA 1910.140, OSHA 1926.502

Yes. The 3M DBI-SALA Perimeter Limiter Leading Edge Anchor (2100090) is purpose-built for exactly that situation. It's a freestanding, counterweight-based anchor that provides an overhead tie-off point for up to two workers where no permanent overhead anchor exists. Its tall 7.5 ft (2.3 m) mast raises the anchor point to minimize fall distances and reduce dangerous swing falls at a leading edge, and it conforms to OSHA 1926.502 and OSHA 1910.140. It's ideal for construction decks and similar leading-edge work.
The 3M DBI-SALA Perimeter Limiter Leading Edge Anchor (2100090) conforms to the requirements of 29 CFR OSHA 1926.502 (fall protection systems criteria) and OSHA 1910.140 (personal fall protection systems). It's a reusable, steel anchorage connector with a rated capacity of 310 lb (141 kg) for use with personal fall arrest systems.
It's a freestanding, non-penetrating anchor that uses a counterweight base instead of attaching to the structure. The unit is craned into position on the deck, then simply pushed to the desired spot and it's ready to use. A tall 7.5 ft (2.3 m) mast and anchorage arm provide an overhead anchor point for up to two users, minimizing fall distances and reducing swing falls. The mast and arm rotate around the counterweights so the anchor can be repositioned nearby without moving the whole unit.
Up to two users can tie off at once. The 3M DBI-SALA Perimeter Limiter (2100090) has a rated weight capacity of 310 lb (141 kg) and built-in tie-off points for personal fall arrest systems. It's designed to be used together with additional personal protective equipment and is compatible with various fall arrest systems.
Yes. The 3M DBI-SALA Perimeter Limiter (2100090) has two integrated anchor points and a pulley designed for a rescue system. It also comes with pre-drilled holes so an accessory rescue winch and pulley can be added to route a lifeline, giving added safety and ease of use during a rescue.
It's engineered for mobility. The 3M DBI-SALA Perimeter Limiter (2100090) rides on large, foam-filled flat-free tires with up-front push bars, so once it's craned onto the deck a crew can push it across the surface to the next work area. For nearby repositioning, the mast and anchorage arm rotate around the counterweights. Because it's freestanding, no structural attachment is needed to relocate it.
The 3M DBI-SALA Perimeter Limiter (2100090) has a 7.5 ft (2.3 m) tall mast, which raises the anchor point to reduce the fall clearance needed below the working surface. Its overall dimensions are approximately 188 x 74 x 100 inches, and it's built from steel for durable, reusable service.
No. The 3M DBI-SALA Perimeter Limiter (2100090) is a freestanding, non-penetrating anchor: it uses a counterweight base and does not require attachment to the structure, so it minimizes any impact to the installation surface. It's simply moved into position and you're ready to go, and additional weights can be added as needed.
No. SRLs are not included with the 3M DBI-SALA Perimeter Limiter (2100090). It's the anchorage system itself, with built-in tie-off points, and it's compatible with various fall arrest systems — so you add your own SRLs or other personal fall arrest equipment and PPE.
