great for everything

I bought one of these specifically for hanging part of my rack on and i plan on buying more. This biner is perfect for anything you can throw at it except for when you need a locker. It's cheap, so leaving one or two behind isn't gonna break the bank. I would call it a little on the heavy side especially if you're carrying a ton of them, but they provide a lot of bang for the buck when it comes to usefulness.

Solid, simple

  • Familiarity: I've put it through the wringer

These carabiners are great. Very solid construction and simple.
Excellent for clipping gear to you, top roping anchors, or even setting up your hammock or slackline.
In the off chance you find yourself on a route above your reach of completion you can always use this as a bail biner, although I hope that does not happen to you.

golden standard

  • Familiarity: I've put it through the wringer

for anything non-cutting-edge or alpine, these are awesome. Heavy duty, easy to clip, easy to load and tension with. A nice workhorse carabiner

Hammock Support

  • Familiarity: I've used it several times

I've had a few of these for big wall use, but most recently I wanted to upgrade the carabiners on my ENO hammock. These work great. Nice and light and strong.

Slacklining Staple

  • Familiarity: I've used it several times

Bought these for my 1" slack line. These are a great biner for slack line anchors because of how simple they are. I ordered 4 to use with my 80 foot line.

Best carabiner for top roping

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

The oval shape makes these biners perfect for top roping. These are also they are the cheapest oval carabiners around! Simple yet sturdy piece of equipment! No complaints.

Simple and classic

These are great for starting out top roping, quickly increasing your trad rack, or if you can afford it to use as a bail biner. I like to keep a few of them around incase I get turned away from a route.

Great all-around biner

Great for topropes, hauling, anchors, slacklines, and who knows what else.

Mad Respect

  • Familiarity: I've used it several times

The explorers of the rough granite seas used these exclusively, so why not have a few myself? I use them aid climbing and for racking pins/hook sets, and they work great for that.

Novice question...
Why would the oval be...

Novice question...
Why would the oval be more appropriate for top roping, considering the BD Light-D cost $.50 less and rated 5kN higher? Or is it just the visual symmetry when doubled-up and opposed?

Best Answer Responded on

Honestly, you''ll be totally fine with either one, as long as they're opposite and opposed. The symmetry does make it nice to TR trough, but it's not necessary.

Responded on

Thanks! That's what I was thinking, but I also want to clarify something. My rope runs through a pair of opposed and opposite lockers, I use the light D's opposite and opposed to link runners/webbing/cord for the non-moving part of the anchor. Anything that moves get lockers.

The bread and butter for a Big Wall rack. Honestly, they're light, cheap, effective and reliable.

Slam the slack line

These are great if you are building a proper slack line out of 1 inch webbing.
