Petzl  Oval Screw Link

I use these links for fixed anchors on outdoor routes. Sure, hardware store links work and are significantly cheaper but aren't rated to anywhere near the strength of these links. Most importantly for me, I have a number of carabiners with a "keeper pin" to keep the biner from being removed. These links are the only links I've found slim enough to fit in the space between the keeper pin and the biner's spine. I would not recommend these links as a bail biner. The size makes it hard to feed the rope through it directly. A simple aluminum carabiner is cheaper and easy to use as a bail biner.

The Petzl Oval Screw link is a good emergency 'bail biner' for Alpine or Trad climbing. A bit more expensive than the Metolius Quick Link, but 1/3 the weight.

This Petzl 7mm quick link has some advantages. The 7mm is a tad lighter but more importantly the opening when fully open is much larger than the typical 8mm quick link because it is longer. So it will fit over just about anything you would encounter at an anchor. The other thing is that it is narrower than most 8mm ones so that if you were using a tag line there is little possibility an EDK would pull through it eliminating the need for a snag prone reepschnur setup if you have to leave it. Someone else commented that it would be too narrow to bail off of but unless you have very thick ropes I don't see that being an issue. Other people say leaving a carabiner is cheaper. For one an edk would pass through a carabiner and unless you are buying an unrated Chinese carabiner I don't think that is cheaper option.

Please do not confuse this product with a not rated hareware store screw link. This is a EN 362:05/Q & 12275, CE0082, and UIAA rated screw link from Maillon Rapide in France (But supplied through PETZl a very respected climbing company). That is what you are paying for, unlike the cheap not rated link from the hareware store, which if used for personal protection will most likely turn you into a statistic. So please do your homework when choosing personal protective equipment, and NEVER buy PPE from hareware store.

It gets the job done. Don't for get to bring a 12mm wrench! If you over tighten the nut it can develop burs, so don't crank it down.

When establishing and bolting new canyoneering routes this is the quick link that I clip at the hanger. I also carry a couple on my mountaineering adventures as an emergency abseiling anchor building.

It appears that the top male threads on these screw links need cleaning due to fine metal particles or burrs. Otherwise they will not screw fully closed (a few threads remaining at the top). After lightly brushing them with a small copper wire brush, the links now fully screw closed as they should.

Bought theses for the Black Hills, just on the off chance that I might need them. Great quality, but at a price compared to others.

I think everyone should have at least one bail biner on there harness. Better than loosing a [$] quickdraw on an outdoor wall, and can also be used to suppliment chain anchors.

This is about 3x more expensive than those at the hardware store....also has a lower working load of 1100 lbs. Basically a repackaged hardware link with the upcharge...
