Please note, these items are handmade and so each COBRA turns out slightly differently, including differences in color. The pictures are for purposes of illustration only.

Cobra RTC-AW is a flute support accessory which is attached to the body of the flute. It is designed for use with alto and wood flutes.

Cobra RTC-AW consists of a clip, which attaches it to the flute body, and an adjustable thumb rest for the right thumb. Cobra RTC-AW is made of plastic with soft plastic pads so it will not scratch the flute or hurt the hand. The soft plastic pads prevent slipping. There is a metal screw to adjust the thumb rest.

The clip of the COBRA RTC-AW is specially designed to allow placement on an alto or wooden flute in the desired position. If one of the projecting “fingers” of the clip prevents proper placement because of the key mechanism, the “fingers” can easily be separated and that one removed. Just use a sharp implement like a razor blade or box-cutter to cut it off.

Cobra RTC-AW comes in 2 colors: black and silver.

5 out of 5 stars

I bought it for my Baroque flute and it fits and works wonderfully! I have very short thumbs and wasn't able to balance the flute well, which caused issues with technique. Now I can balance and stabilize the flute much better!

Exactly as expected. Fits well in the needed place and keeps my finger where it needs to be. Advice: Don't pick the biggest one if you have big hands. Choose based on the flute. The XL is almost too big on my Alto for where I put my thumb. I think, despite my choice, I managed to get a good fit.

It stays in place pretty well However, I felt the need to add a Velcro dot inside it to keep my thumb from slipping inside the thumb guard

The support is well built and fits my alto flute snugly. I was able to position it to provide the support to stabilize the flute up to the C# which there is a left hand fix for that. This item exceeds my expectations and I am surprised that it was not available in any of my local music stores. I am a Sax player and have played a little flute along the way. Now I have a fighting chance with this beast of a flute. Thank you for the fast shipping and great product.! G. Parks

The Cobra Thumb adjustable support for alto flute works well and helps with supporting the instrument. This item seems to be built well.
