Function
How it works in the path
At 200mm deep and 0.8kg, the shelf itself is light and shallow enough to fit in most touring and studio racks without crowding adjacent gear. It draws no power and takes no rack unitsThe standard slice of rack height: 1U = 1.75″. A 3U box takes three slices; half-rack gear pairs two units side by side in one. of its own in this catalog's accounting, but practically speaking it occupies one full 1U row when combined with its partner panel or device — plan your rack layout accordingly. The shelf uses standard rack earsThe flanges that bolt gear to the rack rails. Desktop boxes without them need a shelf, tray, or drawer to live in the case. and mounts with your normal 10-32 or M6 hardware, so there's nothing exotic about the install. The device sitting on it is typically secured with hook-and-loop or double-sided foam tape, since most desktop gear has no rack ears of its own.

Where it earns its place in the system
This shelf makes sense when you have a compact desktop interface or small utility device that genuinely needs to live in the rack but was never designed for it. It's a practical, cheap solution for a specific problem. If the gear you're trying to mount is full-width or has official rack-ear kits available, skip this and use those — a proper rackmount is always more secure for touring. Similarly, if you're stacking two of these side by side to fill 1UThe standard slice of rack height: 1U = 1.75″. A 3U box takes three slices; half-rack gear pairs two units side by side in one., make sure the combined weight of both devices stays reasonable, since the shelf is built for light desktop gear, not heavy units.
In the rack
Details worth deciding before load-in.
Secure the desktop device to the shelf with hook-and-loop fastener tape rather than double-sided foam — it holds firmly but lets you pull the unit quickly if you need to swap or service it at a gig.
If you're running this shelf solo on one side of the rack, order a matching half-rackThe standard slice of rack height: 1U = 1.75″.

Route USB or audio cables out the rear of the shelf before you rack the unit — the 200mm depth is tight, and trying to dress cables after the fact in a packed rack is a headache you don't need at load-in.
Place this shelf away from high-heat neighbors like power amps or dense DSPDigital Signal Processing — the number-crunching that does EQ, compression, and effects inside a box. More DSP means more processing at once. units; the desktop gear sitting on it usually has minimal ventilation of its own and will run warmer than it would on an open desk.
