Wedge trombone screw rims are available in silver or gold plated brass or Delrin plastic, and are compatible with Doug Elliott ST, LT, XT, SB, and LB cups.
Wedge screw rims have our patented curved, oval design, but are made to match the round DE cup.
Sizes correspond to DE sizing and represent the inner diameter (ID) of the cup in inches measured in the long axis of the oval at .05 inches into the cup.
Example - an XT 101 rim fits a DE XT cup and measures 1.01 inches, the same as a DE rim.
