The slide guard was too tight on a Conn 88H and caused the slide not function easily.
Will fit to my Conn 52H and see if the same effect occurs.
The supplier responded:Thanks for your feedback and letting us know of this. We will investigate the fitting on larger bore slides like yours and perhaps update the description accordingly if there is a size limit. We have sold many of these without an issue but perhaps they are aimed at beginners on straight Tenor Trombones (with smaller bore slides) to stop them from banging them etc. We'll check into it accordingly and thanks for raising it.
