ATTACHE Carabiner

The Petzl ATTACHE is a workhorse among screw-gate carabiners, often found racking alongside pricier options due to its thoughtful design and reliable performance. At 56 grams, it’s not the lightest full-sized locker on the market, but its pear shape and ample gate opening make it incredibly versatile for a range of tasks, from belaying and rappelling to building anchors and general rigging. The H-shaped cross-section helps keep the weight down while maintaining a high strength-to-weight ratio, which is crucial for any piece of gear that sees daily abuse. Its smooth keylock nose is a big plus, preventing snags on ropes, slings, or bolt hangers when you're working quickly or in less-than-ideal conditions.

While its compact size contributes to its packability and makes it less bulky on a harness, it does mean that accommodating a Munter hitch with certain larger diameter ropes can be a tighter fit than with a truly oversized HMS carabiner. However, for most modern ropes up to 10.5mm, it handles belay and rappel duties with ease. The screw gate mechanism is smooth and reassuring, engaging fully with just a few turns, and the red visual indicator provides a quick confirmation that it's locked. This reliability in locking and unlocking is a testament to Petzl’s attention to detail, preventing frustrating jams or stiff gates even after extended use in dusty or wet environments.

Compared to ultra-light wiregate lockers, the ATTACHE offers a significantly more robust feel and greater gate clearance for its weight class, justifying its slightly higher mass for critical applications. It’s a solid choice for climbers and canyoneers who need a dependable, versatile locking carabiner that won’t break the bank or add unnecessary bulk to their rack. It excels as a primary belay carabiner, a crucial anchor component, or a general-purpose locker for connecting gear to your harness or pack.
