DW SMRKML15 Hinged Memory Lock, 1.5 in
The SMRKML15 is a hinged drum memory lock for 1.5 in rack bars. The manufacturer puts nine of them in its main rack package, which says a lot about its role: it sets the height of the structure itself, not of an accessory.
What sets it apart
- For 1.5 in main bars
- Hinged closure around the tube
- Nine of them in the brand's main rack package
- Sets the height of the structure, not just an accessory
- Secures a vertical section against slipping down
- Chrome finish
Rack height, the setting you always have to redo
On a rack, the height of the bars drives everything else: the position of the toms, the angle of the cymbals, the reach needed to get to each piece. It is the first adjustment you make, and the longest to find again.
A memory lock on each vertical leg turns that search into a simple mechanical step: you raise the bar to the stop, and the whole geometry of the setup is back. Every setting that depends on it is right again at the same time.
Why it comes in rack packages
The manufacturer includes nine of them in its main rack package rather than offering them as an option. That is a clue: on a load-bearing structure, the memory lock is not a convenience accessory but part of the system.
If you are building a rack from tubes bought separately, or extending an existing one, the consequence is simple: plan the memory locks at the same time as the bars, not later.
Safety that works quietly
A main bar that slips two centimetres during a gig takes everything mounted on it down with it. You only notice while playing, when the tom is no longer quite where your hand expects it.
The memory lock placed under the clamping point prevents that slip, whatever state the clamp is in. It is passive protection: it asks for nothing, needs no adjustment, and only matters the day something gives way.

Frequently asked questions
- What is the difference from the 1 in memory lock?
- The diameter, and so the part it works on. This one handles the 1.5 in main bars; the smaller one handles the secondary sections.
- Do I need it if my rack is already tightened?
- A clamp holds until it doesn't. The memory lock is there precisely for the moment it loosens, and it saves you hunting for the height every time you set up.
- How many do I need for a rack?
- At least one per adjustable vertical section. Some drummers add them at the horizontal joints to lock in the width as well.
- Can it go on a rack that is already assembled?
- Yes, thanks to the hinge: it closes around the bar without having to take anything apart.
