Modules are screwed into M3 metal nuts placed in the rail's channel. You position the nuts to match your modules' mounting holes.
The base lineup covers 3U/7U, 40HP/60HP and black/white. 7U is 3U × 2 rows + 1U. The rail shape and set contents keep being refined while we build cases.
Material and colour
The rail is built to be filled with metal nuts in its outer part. The outer part comes in two materials, white or black, both resin. White is cheaper but may yellow over time; black costs more but has a nicer finish.
Both are about equally durable. The material is hard, but please be aware that a strong impact can crack it. Compared with metal, it will crack if you bang it hard against a desk, but it is plenty strong enough to carry a case full of modules.
Metal nuts
Each metal nut is about 1HP wide. More precisely: we found a nut exactly 1HP wide and wondered whether a rail designed around it could be made cheaply — this rail is the result.
Filled completely, a 40HP or 60HP rail takes about one extra nut. Once you have put in about that many, count them and make sure you have 40 (or 60).
These are tiny mass-produced parts, so their shape varies a little. Some slightly oversized nuts are mixed in, and they can be hard to slide into the rail — like the one in the photo, with a little extra metal sticking out at the edge.
The rail is plastic, so forcing a nut in usually works out, but if a misshapen nut goes in near the start or the middle, the nuts after it become hard to insert. You may then apply too much force, which can break the rail.
If you find a misshapen nut while filling the rail, please set it aside. For this reason, a few spare nuts are included in every set.
Besides this metal-nut rail, a nylon-bar version is also in the lineup — please take a look at it too.
3D preview
Switch the height, width, mounting method and rail colour, and see the rail assembled and taken apart, including the screws that hold the rail and the parts inside it. Colours and surface finish differ from the real product. The viewer's labels are in Japanese.

Parts and dimensions
Choose a size and mounting method, then pick a part above the drawing to check its shape and dimensions. Single rails, double rails (for the middle of 7U), the inserted parts and the frames are included. Use the icons on the right to zoom, compare or go full screen. The viewer's labels are in Japanese.
