The new SB Tray is extraordinary light (10g) and nonmetallic, and it has small hooks on the end of the two protruding prongs that clip inside the bottom caps of valves one and three, giving a very secure and reliable grip. This model has the adjustable “hooks” to allow for the different dimensions of different brands of tubas. The SB-Tray will catch any drips and grime of water and oil and muck that often spoil an instruments appearance and also ruin your clothes. Please see the sizing guide and measure the gap to ensure you order the correct size for your instrument. The key measurement is the distance between the outside edges of the valve holes, on valves one and three. Shown as “Width Measurement A” on the diagram. As long as your instrument falls within the range specified, your SB-Tray should fit. This is the model to fit on euphoniums with flat bottom caps.
