Just installed this on my Ludwig Centennial 26" bass drum. Using it to hold the ride cymbal.
It was a piece of cake to install, up and running in minutes. Replaces one of the lugs on the drum. The technology in the Atlas Mount Bracket, a series of rubber bushes and internal springs ensure that any overtones from the cymbal are not transferred through the unit into the drum.
A solid piece of kit with the brilliant Atlas finishes that match the rest of my set-up. It also comes with a memory lock with a cool Keystone logo in the centre.
I have installed the Atlas Mount in conjunction with the Aerodyne Tilter Clamp - Long (LAP3T6) and a Gibraltar SC-LRL-1 Extra Large L-Rod. This set-up has no problem supporting the weight of the ride cymbal ( a Paiste 2002 20").
This allowed me to replace a boom stand that was over-extended and would often fall over during playing.
Highly Recommended.
