Typical DW build quality and attention to detail. In comparison to other kick drum hoop clamps, the DW clamp has a claw which fits over the edge of the hoop and the drum head collar ring, creating a very solid and stable mounting point with minimal risk of damage to the kick drum hoop.
The claw has a felt insert to help resist damage to the hoop edge, but I added a small strip of rubber in addition to give added protection to the hoop edge. I'm not sure this is really needed as it is not necessary overtighten the claw - just snug it down so that it grips the hoop securely without digging into the hoop edge.
The claw comes with an L rod (9.5mm on one side, 1/2 inch on the other), and either end can be mounted in the v-clamp on top of the claw, therefore suiting a wide variety of percussion mounts.
Helpfully, the L-rod is supplied with a hinged memory lock for the 1/12" part of the rod. This is great, but I wish that DW had also supplied a memory lock for the 9.5mm rod too.
Overall, very happy with this purchase, which is a much better solution than typical clamps which grip both flat sides of the drum hoop and which will damage the hoops eventually.
