How to Install ring guards. Ring guards are designed to help your ring fit better around your finger. Arthritis and many other conditions can cause knuckles to become enlarged. That means your ring has to be big enough to fit over your knuckle, but then it's too big for your finger. Installing a ring guard is the perfect fix to this common problem, and they're readily available for you to purchase.
Purchase a ring guard. They're available at many local jewelry stores, or you can find them online. Ring guards are available in gold and silver to match whatever ring you choose.
Place the ring guard next to the ring. The ring guard is shaped so the edges turn upward to match the existing contour of the ring.
Put the ring guard inside the ring. Push down on the ring guard so it takes the same shape as the ring.
Tighten the ring guard to the ring. You can do this with a regular pair of needle nose pliers.
Clamp down on the arm of the ring guard once it's wrapped around the ring. This tightens the ring guard so it doesn't slip.
Repeat the process for the other side of the ring guard.
Adjust the size of the ring to your liking. Push up or down in the middle of the ring guard to find the fit that's right for you.
