Will this fit my non-Buffet clarinet?

While we only guarantee our kits will fit Buffet clarinets without modification, they can be easily adapted to other brands of clarinet by a qualified technician. If you are interested in doing so, please have your technician reference the notes below to see if the key can be installed with no modifications.

For Technicians:

You will need to take the following measurements to see if the key and arm can bolt onto a non-Buffet clarinet with no modification. If the clarinet you would like to adapt the key to is out of spec, follow the instructions below:
Left-hand F#/C# hinge tube outside diameter: .115" - .133"
Hinge tube too large - Sand or turn the hinge tube exterior on a lathe (do not ream the hole in the e-flat key)
Hinge tube too small - Usually not an issue, but consider machining an adapter sleeve
Distance between the LH F#/C# hinge rod centerline and the E-flat pad cup centerline: 2.05" - 2.09"
Distance too long - Remove the nylon pin. Using a piece of drill rod, ABS, or nylon, make a longer pin that extends farther from the key. If using drill rod, wrap in heat-shrink tubing to silence
Distance too short - Remove the nylon pin. Key can be ground shorter and pin re-installed.
Length of the LH F#/C# hinge tube (between the key face and the post): .242" - .270"
Hinge tube too short? The rectangular boss can be filed down until the key fits
Hinge tube too long? While this will work, the key will be noisy. Consider machining a small washer to be used between the E-flat key and the existing F#/C# key.
