Our stainless steel D rings are ideal for use on pet collars, horse tack, purse straps, harnesses, belts and other DIY craft projects. These metal dee rings are often used as bag hardware and briefcase hardware for joining the shoulder strap to the bag or case. These strong D-rings are solid cast for strength and safety as opposed to rings that have a joint which are weaker. The 1 1/2 inch size is the inside diameter measurement so you know how much space is available to accommodate your leather strap or webbing.
I buy it for collar for very strong dog, and I am sure this D-ring can hold the biggest dogs.
