DW SMRKC1515 90-Degree Drum Rack Clamp, 1.5 in to 1.5 in
The SMRKC1515 is a structural part. It joins two 1.5 in rack tubes at a right angle, with no adjustment, and that is what makes it the corner of a drum rack: the part that has to hold the shape while everything else is mounted on it.
What sets it apart
- Joins two 1.5 in rack tubes
- Fixed right angle: the rack's geometry does not drift
- Serves as a corner or a crossing in a structure
- No joint, so no play to take up
- Chrome finish
Structure and mounting, two different jobs
A rack breaks down into two kinds of parts. The ones that build the shape — corners, crossings, legs — and the ones that hold something on it. Mixing them up is the most common mistake when building a first rack.
This clamp belongs to the first kind. It takes neither an arm nor a tom: it gives the rack its angle and its rigidity, and that rigidity is what allows every mounting clamp to do its job properly.
Why the right angle should not be adjustable here
On a mounting part, an adjustable angle is an advantage. On a structural part, it is a weakness: every degree of freedom is a degree through which the rack can close or open under load.
A rack holds its shape because its corners are fixed. It is the same principle as a timber frame: you use brackets, not hinges. Adjustment comes afterwards, on the parts that carry the instrument.
The crossbar and what it carries
Once the corner is in place, the horizontal bar becomes the support for everything else: toms, cymbals, percussion. Its rigidity depends directly on how well its ends are held.
A bar poorly held at its end starts to vibrate as soon as you hit a tom mounted in the middle. That vibration travels to everything attached to it, and it is fixed at the corners, never at the clamps.

- Adding a perpendicular branch to a rack already in place
Compare with other manufacturers
Structural clamps exist from every rack maker, with diameters that do not mix:
| Manufacturer | Comparable model | What differs |
|---|---|---|
| Gibraltar | Rack system right-angle clamps | Several tube diameters in the catalogue |
| Pearl | Rack right-angle clamps | Bar geometry specific to the brand |
| Tama | Rack structure clamps | Different clamping profiles |
Frequently asked questions
- Can I mount a cymbal arm on it?
- That is not its job: it joins two 1.5 in tubes together. To mount an arm, you need a clamp that offers a receiver.
- Does it fit a tube of a different diameter?
- No. It is sized for 1.5 in on both sides; a thinner tube would not be held properly.
- Can it go somewhere other than the end of a bar?
- The manufacturer does not say: it lists it as a 1.5 in to 1.5 in clamp at 90 degrees, without specifying a position. It is therefore something to check on your bars during setup.
- How many do I need for a rack?
- It depends on the design: a U-shaped rack needs two corners, and a structure with a side branch needs one more per branch.
