These Standard Split Rings from Simplr are made from a unique aerospace-grade steel/magnesium alloy and are 25% stronger than stainless steel. Unlike stainless steel or titanium, these round spring-tempered split rings always spring fully-closed. They're burnished and tumbled for smoothness, then nickel-plated for corrosion resistance. These rings have a tensile load capacity of 60 pounds, and are ideally sized for 3/8" wide strap webbing, the width used on most camera straps.
