NBSK 50120 Quick Steel Shackle 😅⛓️ Faster pin action for real tree work
Honestly, if you’ve ever spent extra time wrestling with hardware at height, you already get why a “quick” rigging connector matters. This steel shackle is designed to help you build secure connections for common arborist setups—without adding a bunch of bulk to your kit.
Tip: Always verify compatibility with your system and follow your site’s rigging practices.
What it is (and why it’s useful)
The NBSK 50120 is a heavy-duty arborist connector built for making secure connections in setups like basal anchor connections, canopy redirects, and other rigging workflows. The biggest appeal is the rotating pin design (quadruple action) that’s intended to reduce friction during operation—so the hardware move feels smoother than a standard quick link when you’re trying to work efficiently.
Quick reality check
At some point, every climber ends up balancing speed with careful rigging. This shackle is intended for professional-grade tree climbing and rigging hardware use, but you still need to size it correctly, inspect it regularly, and rig the system the way your training and manufacturer guidance call for.
Key Features
- Rapid rigging solution: Designed for creating secure connections for basal anchors, canopy anchors, and redirects.
- Rotating pin designed to reduce friction: Intended to help you operate faster than a standard quick link during setup.
- Heavy-duty & compact steel form: Major axis rating of 30kN (6,700 lbs) in a compact design intended to reduce bulk in your gear.
- Quadruple action pin: Engineered for secure connection behavior during professional rigging tasks.
- Versatile arboriculture use: Commonly used with arborist ropes and friction savers to build basal anchors or redirects in canopy rigging.
Why This Product Exists
This is basically for people who do tree climbing and rigging for a living (or close to it) and want the connection hardware to feel more efficient in the moment—especially when you’re working at height and every extra second with stubborn hardware adds up.
If your workflow includes basal anchors, canopy redirects, or multi-step rigging where you need dependable connectors, a purpose-built steel shackle like this can fit right into the routine.
Best Fit For
- Professional arborists and serious tree care workers who need reliable rigging connectors.
- Tree climbing setups that use basal anchors and/or canopy redirects.
- Workflows where compact hardware helps keep your gear manageable.
- Riggers looking for a rotating pin design intended to reduce friction compared to a standard quick link style connector.
Final Verdict
The NBSK 50120 is a compact, heavy-duty steel shackle intended for professional arborist rigging—especially when you’re setting up basal anchors and canopy redirects. The rotating, quadruple action pin is the standout feature, aimed at making operation smoother and faster than a standard quick link. If your kit calls for this style of connector, it’s a solid, practical upgrade to consider—just make sure it matches your rigging plan and inspection routine.
