Bolt-on Alternate A-flat/E-flat Lever

Exactly what I needed. I added this to my Backun Alpha Bb clarinet. I took it to my repair man because did need a bit of shaving to fit right but once it was sanded down it fit like a glove. It adds only a little weight to the right hand Eb/Ab pinky ley. It can be adjusted to the height of your liking, depending on where you want to press and how much space you’d prefer on the left pinky B/C# keys. This piece works amazing and really gives the added facility that is needed in certain situations. Thank you for such a beautiful product!
