Bach Leather Valve Guards fit all Bach and most other brands of trumpets and cornets, including instruments with triggers
I very much enjoy using this valve guard! I have a black lace valve guard for my Bb trumpet and a tan one for my C trumpet. This valve guard is particularly easy to use as it doesn't push my hands away from holding the horn properly thanks to it being so thin. I also notice no change in the sound quality of my horns which is often a problem with other valve guards. This is a great product and I would suggest it to anyone who is looking to keep their valve casings clean while still being able to hold the horn however they see fit.
