The Mad Rock Super Tech Keylock Screw is the best value for lightweight carabiners. It scored only a little lower than the Wild Country Neon but costs much less. If we were loaded, we would go with the Neon exclusively with a few Petzl Attache 3D here and there. But if you are on a budget, then it's hard to beat this carabiner for its weight and the money. The only other $8 light carabiner is the Black Diamond Quicksilver Screwgate, which is heavier and does not have a key-lock gate.

This is a very light carabiner (almost the lightest). While it is small and compact, it has an I-beam design that makes it easy to handle. It is the perfect carabiner to load up on for multi-pitch climbing because it is so light.


There are no major dislikes other than that since it is a small carabiner, it doesn't have great gate clearance or hold much. It is also not good for belaying the second from the anchor.

Best Application

A lightweight all around locking biner best for uses where size and weight are a key factor.


This is hands down the best value in small locking carabiners.

I recently overhauled my rack with lightweight everything, and dropped a ton of weight. I swapped out (almost) all my locking carabiners with the Mad Rock Super Tech. As the SuperTopo review says - the only drawback is that it is a small carabiner - thus gate clearance and overall capacity is somewhat limited.

I carry a couple larger HMS-style carabiners (also Mad Rock ultralights) for Belaying, and a Master Point. But for everything else - I use these. I even have a couple draws with these lockers on them for added safety - they weigh less than many non-locking biners!


Bottom Line: Yes, I would recommend this product to a friend.
