JRSGS Locking Climbing Carabiner Clips – 7075 Aluminium D-Shaped Pair, 25 kN Strength, Knurled Screw-Lock

JRSGS Climbing Carabiner Clips are D-shaped, UIAA-rated locking carabiners made from 7075 aviation aluminum with a 25 kN major-axis strength for climbing, rescue, camping, hunting, and heavy-duty tethering.

This pair of locking carabiners combines industrial-grade strength with lightweight portability. Crafted from 7075 aviation aluminum and finished with an upgraded knurled locking nut, these clips are sized for one-handed use and designed to perform in technical outdoor activities such as rock climbing, rope rescue, tree climbing for hunting, hammock suspension, and carrying heavy loads like securing large dogs. They balance durability, secure closure, and ease of operation so you can move confidently on ropes and at height.

How strong and safe are these carabiners?

Each JRSGS locking carabiner meets UIAA-style strength expectations with a 25 kN (5,621 lb) major-axis rating and a 7 kN cross-load rating. The D-shaped body directs load toward the spine for improved strength under tension, and the threaded knurl nut provides a positive mechanical lock.

• 25 kN spine strength (major axis) for primary load-bearing tasks
• 7 kN cross-load resistance for improved lateral stability
• D-shaped geometry to concentrate force along the strongest axis
• Double-layer knurled nut for secure screw-lock action

Will these carabiners be easy to operate during climbs or rescues?

The design favors one-handed operation: a 0.67-inch gate opening and ergonomic D-shape let you clip ropes or gear while maintaining balance. The upgraded knurl nut increases friction so you can lock and unlock the screw with finger pressure, even when wearing thin gloves.

• 0.67" gate opening for quick clipping of ropes and straps
• 3.93" length and 2.2" width for secure handling and leverage
• Knurled double-layer nut for improved tactile grip
• Lightweight at 59 g (2.2 oz) to minimize carry load

What materials and dimensions should I expect for performance and weight?

These carabiners are stamped from 7075 aviation-grade aluminum, chosen for its high strength-to-weight ratio. At 59 grams apiece, they add minimal weight to a harness or pack while offering industrial-level strength for demanding applications.

• 7075 aluminum construction for high tensile strength and low weight
• Net weight roughly 59 g (2.2 oz) per carabiner
• Overall size: 3.93" long by 2.2" wide to fit most harnesses and slings
• D-shaped profile for optimal rope alignment and gear stacking

How should I maintain and inspect these carabiners?

Routine visual and tactile checks will keep the carabiner functioning as intended. Look for deformation, cracks, corrosion, or damaged threads; clean grit from the screw mechanism and lubricate lightly if needed, and retire the carabiner if any structural damage is present.

• Inspect before each use for cracks, sharp edges, or thread damage
• Rinse salt or dirt away with fresh water after marine or dusty use
• Use a dry graphite or silicone lubricant on threads if sticking occurs
• Do not use if any deformity or deep gouge is visible

Who is this for?

JRSGS locking carabiners are built for climbers, rescuers, arborists, hunters, hammock users, and outdoor professionals who need a dependable, lightweight connector rated for serious loads. They suit both recreational climbers seeking durable hardware and technical users who require UIAA-style strength and a reliable screw-lock mechanism for work at height or heavy tethering.
