Snap Shackle vs. Carabiner: Which Quick Release Shackles Do I Need?
Snap shackles and carabiners (also called carbine hooks) are both popular quick release shackles for the industrial sector. They share the same basic purpose of providing a quick and reliable point of attachment. So, what’s the difference? And which is right for me?
A QUICK-RELEASE SHACKLE COMPARISON:
As stainless steel hardware, both designs are capable of being load-rated for incredible maximum loads. Both designs are far simpler to release than traditional shackles with threaded bolts but differ in their opening and connection style. Because an open carabiner is accessed through the side, it can still be difficult to release under load. Conversely, a snap shackle’s bail can swing wide open allowing easy clearance when released regardless of load.
- Releases easily under tension
- May include a swivel or trunnion
- Smooth release plunger secured by a spring (unthreaded)
- Immediate, sudden release via mechanical plunger
- Must overcome tension to release
- May include a threaded “locking sleeve” to prevent accidental release
- Simpler to operate (just push open the gate), but release requires manual removal of the line.
- Hook opens inwards for added security

- High Strength to Weight Ratio: Exceptionally high working loads for their size.
- Two Finishes: Available in a polished finish or black oxide.
- All Stainless Steel Design: For extreme durability, no corrosion, and continued use in the harshest environments.

Ronstan Industrial’s snap shackles and carabiners are all made with the finest materials and have been tested and approved for use in the harshest outdoor environments. Snap shackles can be more expensive, but when you need to release in an emergency or under load, they can have a huge advantage over a carabiner. This has led them to become popular with divers for securing their tether lines and communication ropes. On the other hand, carabiners are sometimes preferred when the priority is to avoid accidental release, making them a favorite among climbers.
While not intended for human suspension, Ronstan’s products are ideal for marine and outdoor applications as well as fast attachment of tools, lanyards, and equipment. They’re ergonomically designed for simple and reliable operation with the materials and craftsmanship to ensure a long and productive service life.
