These D-rings are O.E.M. replacements and may be slightly bigger the originals. These do not come with glue! We recommend using HH-66 vinyl cement glue available through Amazon.com. Replacing broken D-rings is easy! You'll need to mask off the work area around the D-ring well. Then use a little acetone or basic paint thinner to get the old material off. A green scrub pad helps to get the old glue off and will make the SUP material a little tacky and discolored-but that's what you want for good adhesion of the new glue. Spread some of the HH-66 glue on the D ring patch and position in place. Use some tape to hold it in place while it dries. It takes 48 for the glue to cure and then you can tie the bungee back on and be good as new.
