EDELRID HMS Strike Locking Carabiner - Triple Lock Silver/Icemint Review (2026)

What the HMS Strike Triple is built for

The HMS Strike Triple is EDELRID's pear shaped, or HMS, locking carabiner aimed at belaying, rappelling and anchor work where a wide gate opening and a self closing lock matter. The HMS profile is intentionally roomy compared with a D shaped locker, which is what lets it accept a Munter hitch, a tube style belay device, or several strands of rope and slings at a busy anchor without everything bunching against the spine. EDELRID builds it with a keylock nose, a notch free design that keeps the gate from snagging on rope, slings or a harness belay loop during repeated clipping and unclipping. It is aimed at climbers who want an auto-locking gate rather than a manual screwgate they have to check and tighten themselves at every belay transition.

Strength, weight and the triple lock mechanism

According to EDELRID's published specifications, the HMS Strike Triple carries a major axis strength of 22 kilonewtons, a minor axis strength of 8 kilonewtons and an open gate strength of 7 kilonewtons, all comfortably above the minimum a certified locking carabiner needs to meet under EN 12275. The gate opening measures around 19 to 21 millimeters depending on the source, wide enough for a Munter hitch or a tube device with a thicker rope. As a triple lock carabiner, the gate closes and locks itself automatically, and opening it requires a deliberate combination of motions rather than a single push, which is meant to make an accidental opening far less likely than with a basic screwgate sleeve.

Using it at the belay and on the rack

At a hanging belay or a busy multi pitch anchor, the wide HMS shape gives enough room for a Munter hitch, a belay device and a cordelette without constant repositioning, and the auto-locking gate means there is no sleeve to forget to tighten before weighting the system. EDELRID notes the carabiner includes a spring bar element intended to stop it from twisting sideways when racked on a harness or sling, which keeps the gate oriented correctly for a quick clip. The trade-off climbers report with any triple lock design is that the extra motions needed to open the gate can feel slower with cold hands or gloves than simply unscrewing a sleeve, so it rewards practicing the opening sequence before it matters on route.

How it stacks up against other HMS lockers

Against Petzl's manual screw-lock William, another large pear shaped HMS carabiner built for anchor building, the Strike Triple trades a slightly higher major axis rating for the convenience of an auto-locking gate instead of a sleeve a climber has to check by hand. Against a compact belay-specific locker like Black Diamond's RockLock, the Strike Triple is bulkier and heavier since its HMS shape and triple lock hardware add material the RockLock does not carry, but that bulk buys a wider gate and multiple points of contact for anchor work. Climbers who want one carabiner dedicated to a compact belay device such as a GRIGRI may still prefer a narrower locker over the Strike Triple's roomier profile.

Who should buy the HMS Strike Triple

This carabiner suits climbers who belay often, build multi pitch anchors, or want a Munter hitch option without a device, and who would rather have a gate that locks itself than remember to screw a sleeve shut every time. The icemint and silver colorway also makes it easy to pick out from a rack of black or grey hardware at a glance. Climbers who prioritize minimum weight over auto-locking convenience, or who mainly clip a single compact belay device, may be better served by a lighter screw-lock or a narrower HMS locker like the RockLock. Given our score of 8.6 out of 10, it earns its place as a dedicated belay and anchor carabiner rather than an everyday rack locker.
