  • 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.
