Frequently Asked Questions
What is an autolock carabiner?
An autolock carabiner features a gate that automatically locks closed when released, without requiring the user to manually rotate a sleeve. This reduces the risk of accidental gate opening during climbing or rigging operations, making it a preferred choice for safety-critical applications.
What does 25kN MBS mean?
MBS stands for Minimum Breaking Strength — the minimum force at which the carabiner is rated to fail under laboratory testing. 25kN is approximately 5,600 lbs, which is well above the forces encountered in typical arborist climbing and rigging use.
Is aluminum suitable for arborist rigging?
Yes. Aluminum carabiners are widely used in arborist climbing systems for their excellent strength-to-weight ratio. For heavy rigging loads or high-friction applications, a steel carabiner may be preferred — but for climbing and work positioning, aluminum is the industry standard.
How does an autolock gate differ from a screwgate?
A screwgate requires the user to manually thread a locking sleeve to secure the gate. An autolock gate locks automatically on release, which is faster and reduces the chance of forgetting to lock the gate — a key safety advantage when working at height.
What applications is this carabiner suited for?
This carabiner is well-suited for arborist climbing systems, work positioning lanyards, friction hitch setups, and general rigging connections where a lightweight, reliable autolock gate is needed.
