DW DWSMRKML15 DW Rack 1.5-Inch Hinged Memory Lock

This DW memory clamp works exactly as expected. It marks your place on the rack, and adds extra hold/ security for your rack clamps. I've used it on Tama and Gibraltar 1.5" rack tubing. Instead of having a built-in wingnut, the tightness is adjusted with a drum key. It's low-profile and unobtrusive. I'd buy it again.

Obviously, aesthetically these are designed to match DW or PDP drum rack clamps, but functionally they will work with other brands like Gibraltar and Sound Percussion. Some memory locks only have two "posts", I like the functionality in these having four, which makes it more versatile when it comes to mounting positions.

Fits and works well.

Works fine
