First, fit the stand onto your sax, and check if the bow support of the stand doesn’t interfere with any of the protection brackets on your sax when properly placed into the padded fork. As it is now , in the center hole, it will fit most alto’s, but you can take it off, and simply move it in a lower or higher position. The bow support may also be helpful to slightly alter the angle of your instrument once the stand is mounted.
Furthermore you should decide where you want your instrument to be mounted. You could hold it up in front of the wall with your instrument in it in the preferred position, and have someone else mark the holes and mount the stand accordingly.
I strongly suggest mounting the stand so that the main body of your sax is positioned between the 1 and 7 on a clock face, but certainly less angled than between 2 and 8!
I recommend putting one screw in first, and double checking the angle with your sax in it before putting in the other ones.
Make sure you hold on to your sax while doing so !!!
You can use up to 6 screws although 3 will be plenty. 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 drill bit and insert the wall plugs and screws.
If you use a cordless drill for the screws, make sure its chuck doesn’t damage the coating.
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 occasionally very lightly spray a soft cloth with some silicone spray and give it a rub. It will turn a deep black again!
