US Rigging Aluminum Tri-Act Swivel Carabiner — 25kN MBS
Rope twist is one of those slow, frustrating problems that builds up over a long day in the tree — and the integrated swivel on this carabiner is the fix. As you move through the canopy, the swivel allows your climb line to rotate freely, preventing the torsional buildup that makes ropes stiff, tangled, and harder to manage. Paired with a Tri-Act locking gate that requires three distinct actions to open, you get a carabiner that actively works to keep your system clean and your focus on the work. Aluminum construction keeps weight down without sacrificing the 25kN MBS you need.

Frequently Asked Questions
Why does a swivel carabiner matter for arborist climbing?
As a climber moves through a tree, the climb line naturally accumulates twist from changes in direction and body rotation. Over time this twist makes the rope stiffer, harder to manage, and can affect the performance of friction hitches and rope grabs. An integrated swivel allows the rope to rotate freely at the connection point, continuously relieving twist before it builds up.
What is a Tri-Act gate?
A Tri-Act gate requires three sequential actions to open — typically push, twist, and pull. This triple-action mechanism makes accidental gate opening extremely unlikely, even under vibration or repeated contact with other equipment, making it a preferred choice for safety-critical climbing connections.
Can I use this carabiner at my saddle connection point?
Yes. The combination of swivel, Tri-Act gate, and 25kN MBS makes this carabiner well-suited for use at the saddle bridge or dorsal connection point, where rope twist management and gate security are both important.
How does this differ from a standard Tri-Act carabiner without a swivel?
The swivel adds active rope twist management that a standard carabiner cannot provide. If you're climbing with a stationary rope technique or frequently changing direction in the canopy, the swivel version will noticeably reduce rope management issues over the course of a workday.
What is the MBS rating on this carabiner?
MBS (Minimum Breaking Strength) is 25kN, approximately 6,720 lbs — well above the forces encountered in typical arborist climbing and work positioning applications.
