								 ST series: Smaller Tenor trombone rim sizes 
								for small bore trombones and alto trombones 
								The ST series has a general "feel" about like an 11C or 12C  
								Rims: 
								ST 94 similar to Bach 22 (23.9mm) 
								ST 95 similar to Bach 17 (24.1mm) 
								ST 96 similar to Bach 12, Wick 12CS (24.4mm) 
								ST 97 similar to Bach 11 (24.6mm) 
								ST 98 similar to Bach 7, Wick 10CS (24.9mm) 
								ST 99 similar to Bach 9, Bach 6?C (25.15mm) 
								ST 100 similar to Bach 6?AL, Schilke 48 (25.4 mm) 
								Other sizes also available: 101, 102, 103, 104.  Also Narrow rims in those sizes. 
								Finishes available: S-silver, G-gold, L-Lexan (polycarbonate plastic) 
								Rim contour is Standard. 
								Cups: 
								ST A very shallow, very bright sound, too shallow for most players 
								ST B shallow, for bright sound on small bore trombones 
								ST B+ uses C shanks 
								ST C medium-shallow, for all small bore trombones 
								ST C+ an interesting and versatile cup halfway between C and D, use D shanks 
								ST D medium, for all-around small to medium bore trombone playing 
								ST D+ uses D+ shanks 
								ST E medium, for all types of playing 
								Small shanks: (for small tenors, altos, and small shank euphoniums) 
								alto S - backbore for most Eb alto trombones, slightly smaller taper than tenor to go in farther 
								alto - backbore for Eb alto trombones with normal tenor taper 
								2 - backbore for .485 to .500 single bore trombones 
								2.5 - new backbore for dual bore trombones like King 2B and many Olds small shank trombones 
								3 - backbore for .508 to .510 bore trombones 
								4 - backbore for .525 bore small shank trombones, and euphonium 
								Large shanks can be used, but this series does not work very well on large bore instruments.  
								Notes for ordering shanks: The letter on the shank must match the letter on the cup: for example, a standard small shank for a D cup is a D2. All shanks should fit into the receiver 1". The standard small shank fits almost all small tenors and altos. For Conn 36H altos and other smaller receivers specify smaller "s" shank (goes in farther). Large shanks: not recommended; the ST series does not work very well on larger bore instruments.

								MT series: Medium Tenor trombone rim sizes 
								for small bore trombones and alto trombones 
								The MT series has a general "feel" about like a 7C.

								4 - backbore for .525 bore small shank trombones, and euphonium 
								Large shanks can be used, but this series does not work very well on large bore instruments.  
								Notes for ordering shanks: The letter on the shank must match the letter on the cup: for example, a standard small shank for a D cup is a D2. All shanks should fit into the receiver 1". The standard small shank fits almost all small tenors and altos. For Conn 36H altos and other smaller receivers specify smaller "s" shank (goes in farther). Large shanks: not recommended; the MT series would not work very well on larger bore instruments.

								LT 99 similar to Bach 9, Bach 6?C, Conn 3 (25.15mm)

								LT 104 similar to Schilke 53, Bach 3G (new), but feels smaller (26.4 mm) 
								All are available in my standard shape and Narrow, which is a thin rim.  Other rims also available at extra charge: 11C, 6.5 AL, 5G, 51D, Remington, and several half-sizes like 101.5, 102.5 
								Finishes available: S-silver, G-gold, L-Lexan (polycarbonate plastic) 
								Rim contours available: Standard, N (Narrow), and several that are copies of popular mouthpieces. 
								Cups: 
								LT A very shallow, very bright sound, too shallow for most players 
								LT B shallow, bright, for a bright sound on small bore or alto trombones 
								LT B+  uses C shanks 
								LT C  medium-shallow, for all small bore or alto trombones 
								LT C+ an interesting and versatile cup, uses D shanks 
								LT D medium, for all-around small to medium bore trombones, or alto

								LT I very deep, mostly for euphonium 
								LT J extremely deep, for euphonium, not for trombone (Limited availability) 
								Small shanks: (for small tenors, altos, and small shank euphoniums) 
								alto S - backbore for most Eb alto trombones, slightly smaller taper than tenor to go in farther

								3 - backbore for .508 to .510 bore trombones 
								4 - backbore for .525 bore small shank trombones, and euphonium 
								5 - very large small shank backbore, especially for .525/.547 dual bore trombones, and small shank euphoniums 
								Medium euphonium shanks: (for some Besson, Willson, and others) 
								6E - for all medium-shank euphoniums, E taper fits medium-shank Bessons and Willsons; others on request 
								Large shanks: (for .547 bore trombones and all large shank euphoniums) 
								8 - standard large shank backbore, best design for most trombones and euphoniums 
								9 - larger backbore, specifically for dual-bore 547/562 trombones 
								10 - extra large backbore, very open, works well on both single and dual bore trombones 
								Notes for ordering shanks: The letter on the shank must match the letter on the cup: for example, a standard large shank for a G cup is a G8. All shanks should fit into the receiver 1". For Conn 36H altos and other smaller receivers specify smaller "s" shank (goes in farther). Large shanks: Bach, new Conn 88H, Edwards, Holton, Shires, and Yamaha trombones, and all large shank euphoniums, use the standard large shank. Older Conn 88H and Blessing B88 trombones require a different taper - specify Conn shank for proper fit. King 4B, 5B, and Benge 190 can use standard, but sometimes need a specially tapered “K” shank for a better fit. 
								Top 
								XT series: EXtra-large Tenor Trombone 
								Symphonic rim sizes, large or small shank, and Euphonium 
								The XT series has a general "feel" about like a 4G

								XT 106 similar to Bach 1?G, Wick 2AL, feels a little smaller inside (26.9 mm) 
								All are available in standard shape and Narrow, which is a thin rim. Other rims also available at extra charge: Remington, and several half-sizes like 101.5, 102.5, 103.5 
								Finishes available: S-silver, G-gold, L-Lexan (polycarbonate plastic)

								XT L same depth as the bass trombone L cups  (limited availability) 
								For euphonium, and for bass trombone doubling, also consider the new EUPH series which gives a bigger sound and generally better results with some of the same larger rim sizes as the XT series. The EUPH series is listed with bass trombone mouthpieces because it uses the bass trombone rim thread size. 
								Small shanks: (for small tenors, altos, and small shank euphoniums) 
								alto S - backbore for most Eb alto trombones, slightly smaller taper than tenor to go in farther 
								alto - backbore for Eb alto trombones with normal tenor taper
