Mounting One Trick Pony

First, please try to ‘fit’ the stand onto your saxophone bell before you mount it.
As it is right now it will fit most alto’s/tenors nicely, but there are always exceptions to the rule.
If your tenor doesn’t fit into the top bracket as snug as you would like, you may gently adjust the top bracket of the tenor stand a little by handto make it wider or more narrow.

The alto stand should be ok as it is.
Do not put in a vice or use tools on it since that could damage the stand.
Furthermore you should decide how you want your instrument to be positioned on the wall. The main body of your sax should form a line between the 1 and 7 on a clock face. You can hold it up against the wall with your instrument in it in the preferred position, mark the top hole, put 1 screw in, choose the final position, mark the holes and mount the stand accordingly.

Especially with drywall it is of utmost importance to find a spot that offers solid footing for the screws, and has a stud or beam directly behind it. For stone walls you will have to drill holes with a 5 mm or 3/16 inch drill bit and insert the wallplugs and screws. The little caps are to cover the screws. Put hem on the tip of your forefinger and place them over the screw’s head. Then, with a twisting movement of your finger feel for their proper position over the slot, then just push them in. Use some glue if all else fails.
If you use a cordless drill for the screws, make sure its chuck doesn’t damage the stand.

If for some reason you are not sure how or where to mount it, please contact us or get some professional help!
To keep the rubber in good shape you could put a little silicone spray on a soft cloth and give it a gentle rub.
