Our standard rims measure .650" where they meet the cup and have Giardinelli standard .750"-36 threads. They fit our standard cups as well as those from most US makers.

Inside diameters are measured .050" down from the crown so they may feel slightly larger than other maker's numbers. Widths are measured from .050" down from the crown to the outer diameter. 

In addition to the standard diameter we offer our rims in a "Plus" size. Plus rims have the same .650" dimension at the joint but are .012" wider at the crown.

Our standard finish is gold over silver plate. Gold is hypo-allergenic, non-tarnishing, and feels soft and slippery on the embouchure. Delrin rims are temperature neutral and work well for players who use a dry embouchure. Our plated finishes are very durable and, with normal care, can be expected to last for several years of heavy use.

We can supply any of our rim contours in any diameter. Non-standard silver and gold plated rims take three-to-five weeks. Delrin rims take a week or less. To order a rim in a non-standard diameter email us or call 978 823-0580.
