Draws

Do you retire your draws? When?

10 years for the dogbone/sling is the manufacturers usual line, though some folks do plenty more or less often. Note that you probably don’t need to retire the carabiners unless they are visibly damaged, deeply worn, or sharp. You can buy replacement dogbones for much cheaper than full draws

I retire the carabiners when they get deep enough grooves that they are sharp. For regular draws (meaning not anchor draws) that can take a very long time. 

I have retired draws, or more specifically, dog-bones.  I don't have a specific rule, but a combination of age and wear.  Thin (dyneema) ones seem to get fuzzy and worrisome faster than the nice thick nylon ones.

The carabiners can last forever. I still have one c1977 snap on a QD. What kills them for me is deep nicks (bolts/wires), which polishing out would leave a big groove. 

The dog-bones, 10 years (or when they get badly fuzzy/cut) , they are cheap compared to 2 carabiners.
