The NRS Nuq Screw Lock Carabiner is built for paddlers who'd rather trust a simple, deliberate mechanism than a spring-loaded one when a rescue-kit carabiner actually has to work. Hot-forged from anodised AL-7075 aluminium alloy with stainless steel rivets and wires, it's rated to 28kN closed-gate and certified to CE EN362 and EN12275 — genuinely rescue-grade, and £1 cheaper than its twist lock sibling.
Why Screw Lock — Fewer Moving Parts, Fewer Ways to Fail
A screw lock has no spring and no cam — just a threaded sleeve you turn to lock and unlock. That simplicity is the point: fewer moving parts means less that can jam with grit, freeze shut with ice, or wear out from repeated spring fatigue over a season of hard use. It's a genuine, independently-documented advantage over spring-loaded twist and auto locks for prolonged harsh-condition use, not just NRS's own marketing claim. The trade-off is speed — engaging and releasing the sleeve takes a deliberate two-handed action, slower than a twist lock's instant one-handed clip. For paddlers who've had a spring-loaded carabiner jam or freeze mid-trip, or who simply want one less point of failure in a rescue kit, that trade is worth making.
What the 28kN and 9kN Ratings Actually Mean
This carabiner carries a 28kN closed-gate rating and a 9kN open-gate rating. A kilonewton (kN) measures force — roughly 225lbs — and these figures are the load the carabiner withstands before failing in each state, not a working-load recommendation. The gap between the two matters in practice: a carabiner loaded through a gate that hasn't fully screwed shut is nowhere near as strong as one loaded correctly, so fully engaging the sleeve before loading isn't a formality — it's what the rated strength actually depends on.
Certified for Water Rescue, Built From AL-7075 Alloy
Certified to CE EN362 and EN12275 — connector and rescue-hardware standards, not a claim of suitability for lead climbing or fall-arrest use under climbing-specific standards. Construction is anodised AL-7075 aluminium alloy with stainless steel rivets and wires — a more specific alloy grade than the plain "aluminium alloy" most competing carabiners are described with — at 94g, with a 22mm gate opening and 116mm x 75mm dimensions.
Who Should Choose Screw Lock (and How Many to Buy)
If you're equipping or restocking a whitewater or touring rescue kit — solo, tandem, or as a coach building a club kit bag — this is a certified, mechanically simple locking carabiner that pairs naturally with boats like the Silverbirch Agent 88. A commonly used rescue-kit guideline is 4:3:2:1: four locking carabiners, three pulleys, two prusiks and one length of webbing, with locking types the only carabiner recommended for river rescue — so most kits need more than one. If speed of one-handed clipping matters more than resistance to grit and ice for your conditions, the NRS Nuq Twist Lock Carabiner is the faster-clipping alternative in the same family.

Frequently Asked Questions
What does the 28kN rating on this carabiner mean?
The NRS Nuq Screw Lock Carabiner is rated to 28kN closed-gate and 9kN open-gate — kilonewtons measuring the force it can withstand before failing in each state, not a working-load recommendation. Because the open-gate figure is so much lower, fully screwing the sleeve shut before loading is what actually delivers the rated strength, not just resting the gate closed.
Why choose a screw lock carabiner over a twist lock or autolock?
A screw lock has fewer moving parts than a spring-loaded twist or auto lock, so there's less to jam or fatigue when grit, ice or prolonged wet use gets into the mechanism — a real advantage for a rescue-kit carabiner that has to work first time. The trade-off is a slower, more deliberate two-handed engagement rather than an instant one-handed clip.
Is a screw lock carabiner secure enough for fast rescue use?
Yes — once engaged it's as strong and secure as the twist lock sibling; the difference is speed, not strength. A screw lock takes an extra deliberate turn to lock and unlock, so it suits paddlers who prioritise mechanical reliability over the fastest possible one-handed clip; for genuinely fast in-water rescue work, the NRS Nuq Twist Lock Carabiner trades some of that reliability for speed.
How many carabiners should be in a whitewater rescue kit?
A widely used rescue-kit guideline is 4:3:2:1 — four locking carabiners, three pulleys, two prusiks and one length of webbing — with locking types the only carabiner recommended for river rescue. Most coaches and paddlers building or restocking a kit will need more than one.
What's the difference between the NRS Nuq Screw Lock and Twist Lock Carabiner?
Both are AL-7075 aluminium alloy, CE EN362/EN12275 certified and part of the same NRS Nuq family. The Screw Lock has fewer moving parts and holds up better to grit, ice and repeated wet-dry cycles over time; the Twist Lock sibling trades some of that resilience for faster one-handed clipping, and costs £1 more. Choose based on the conditions you'll actually use it in.
