Key Extensions

In 1994, Brannen Brothers introduced Key Extensions, a tool which allows flutists to reconfigure keys into a more comfortable positions to avert or relieve painful hand problems. These extensions are designed to fit Brannen-Cooper® Flutes and normally will not fit other flutes. Key Extensions snap into the open hole keys and onto the left hand C# key. The G# extension is semi-permanently glued to the G# key and is adjustable. 

 

 

Key extensions offer many benefits:

Adjustable: You can reposition them whenever necessary.

Flexible: Extensions come in three different types and six different sizes. Whether you select one or many, use the exact configuration that works for you.

Removable: If your needs change, or if you sell your flute, extensions can be removed with minimal work.

Inexpensive: Extensions cost less than custom keywork.

Refundable: If key extensions do not provide the comfort desired, return some or all of them within 30 days for a full refund.

 

 

The standard set of Key Extensions includes one each of the six sizes of French cup extensions, one plastic C# extension, and one silver G#extension.The six sizes of French cup extensions are designated as follows:
