Machined DMM rings for friction savers, anchors, and custom climbing setups.
DMM anchor rings are machined rings that arborists use to build friction savers, adjustable tie-in anchors, and other custom climbing setups. The matt grey finish is a low-glare color option that is easy to tell apart from colored rings on a busy harness.
Rings show up all over a modern climbing kit. A pair of rings on a length of rope makes a ring-and-ring friction saver that you can set and retrieve from the ground. A single ring on a sling makes a canopy anchor, and rings are often used on adjustable SRS base anchors and lanyard setups.
Because a ring has no gate, it can take loading from several directions. The smooth bore lets rope and hitch cord run without catching, which matters when you retrieve a friction saver or advance a hitch around it. Having a few spare rings in the gear bag also makes it easy to build a quick redirect or replace a worn ring on a saver.
A neutral matt grey ring is a good way to keep track of which rings belong to which system. Some climbers use one color for friction savers and another for lanyards so they can grab the right piece at a glance.
Check the ring's rated strength and inner diameter before you build a system around it, and make sure it suits the rope and cord you will run through it. See the full range of climbing rings for other sizes and colors.
Retire rings with deep grooves from rope wear, sharp edges, cracks, or any deformation, and after a serious fall or impact. Life-support gear must meet the applicable standard (ANSI Z133 and the manufacturer's instructions), be inspected before every use, and be used only by trained climbers.

Yes, that is a common use. Pair them with a rope or sling and build the saver following the maker's instructions and your training.
No. The finish is cosmetic. Strength comes from the ring's design and material, so check the marked rating.
