When you check out the burly strength ratings on the Mad Rock Hulk HMS Screw Gate Carabiner, it's easy to see where the name comes from. Whenever you're not busy hanging your car over a cliff's edge with this locking 'biner just to show off to your friends, you'll find it comes in handy for setting anchors and generally attaching things to each other. Especially things that you don't want to separate, even under 29kN of force.

  • Familiarity:I've put it through the wringer

This is my favorite carabiner. It's really light and strong and the shape makes it really useful while belaying. I like to have it along in case I forget a belay device so that I can just tie a munter hitch around it and be good to go. You can't really do that on the smaller carabiners. Other than that, the gate action is really smooth, the opening and closing mechanism works great, it's cheap, and the black color is sexy. What's not to love? Just wait till it goes on sale and pick one up: you'll be happy you did!


Good large carabiner

  • Familiarity:I've used it once or twice and have initial impressions

I had a BD Rocklock previously and this one is comparable in size, it's more heavy but feels more solid. The rating is also higher than the Rocklock.

The spring action is heavy and may be difficult for people with small hands to operate one-handed.


Good and cheap standard biner.

  • Familiarity:I've put it through the wringer

This Carabiner is the standard used at my local climbing gym. It gets used daily by hundreds of noob belayers so you know it can stand a beating. It feels lightweight and is rather large. It is your general use biner.


Super Basic

    Basic design, but pretty burly. 29kN is pretty intense, but it doesn't make it feel any heavier than any other biner I've got.
