Why it fits

One device. One mount. No shims, no zip ties.

Designed around one device

Every mount starts as a model built around the real device, so ports, vents and status lights land exactly where they should.

Test fit before it ships

Every design is fit to the real hardware, not a spec sheet. Rack hardware is included when the mount calls for it.

Building a 10 inch homelab rack?

A 10 inch rack, a gateway, a switch, a mini PC and a couple of SBCs is the setup most of my customers are building. Every piece of it has a mount designed to fit, and they all go together in the same rack.

Custom & bulk orders

Standardizing hardware across sites?

Dozens to hundreds of the same mount, for a device I already make or one designed around your hardware.

How custom projects work

Don't see your device?

Most new mounts start as customer requests. Tell me what you're mounting, and if enough people ask for it, it becomes a product and you hear first.
