Rack Leg Brace
The name pretty much says it all!
Leg brace for additional support and stability. Used for standard 1 1/2" to 1 1/2" round rack tubing. Uses tension rods for tightening so once again the only tool needed is one every drummer already has, a Drum Key.
Will work on tubing slightly smaller but larger than that would be a real struggle.
