Simond Spider Screwgate

rated 5.0 of 5 stars
photo: Simond Spider Screwgate locking carabiner

Lightweight, excellent screwgate locker that has a perfectly shaped nose to make clipping extremely easy. The best locking beiner for personal anchor systems at the top of a long difficult route.


  • Nose angle (more open with respect to the spine)
  • Fairly light (medium diameter)
  • Great locking mechanism
  • Metal spring mechanism
  • Smooth nose edge


  • Sacrifice strength for weight and ease of clipping

This carabiner is the best I have used to attach a personal anchor system at the top of a route. The nose is shaped in a way that it is quite open (bent out) compared to other screwgate lockers, so clipping is extremely easy. The diameter of the carabiner is around  a medium sized thickness. Since the body of the carabiner is round and not an I-beam construction you do lose some strength, but the diameter is great if you have to clip multiple pieces of gear onto a single anchor. The carabiner is fairly light for a screwgate locker so you barely even feel it on your harness.

One of the most important factors to me when selecting a carabiner is the spring mechanism. A lot of carabiner manufacturers are using plastic spring mechanisms. I do not like this as I have heard of the spring mechanisms becoming brittle in cold weather. The Simond Spider Screwgate uses a metal spring, this is preferred as a metal spring I believe is more durable.

I have used this carabiner for personal anchor systems in the Canadian Rockies on single pitch sport climbing routes.
