3U Aluminium Enclosure for Custom Builds

This 3U aluminium enclosure measures 131 x 178 x 305 mm externally and 127 x 158 x 285 mm internally. It is built from AL 5052 alloy and conforms to IEC-60 297-1. The open-frame design gives direct access to mounted components. It arrives flat-packed with two extruded mounting bars, four rubber feet and all screws included.

Suits Prototyping and Industrial Projects

The light, strong chassis works well for hobbyist prototypes, test rigs or permanent industrial installations where ventilation and easy panel access matter. Builders who need a sealed, waterproof housing or integrated power supply should look elsewhere, as the extensive top, bottom and side vents leave the interior exposed.

Quick Assembly with Four Screws

The snap-together frame needs only four M3 screws to lock the side frames to the front and rear panels. Mounting bars sit 10 mm below the top or bottom cover; fitting both covers reduces usable height by 20 mm. Rubber feet press into pre-drilled holes on the bottom panel. No special tools are required beyond a Phillips driver.

Questions about this item

What screw sizes are needed to assemble the 3U enclosure?

The kit supplies four M3-6 umbrella Phillips screws and four M4-8 umbrella Phillips dog-point screws; no other fasteners are required.

Will the included component mount bars fit equipment designed for the IEC 60297-1 rack standard?

The enclosure conforms to IEC 60297-1 and the two AL 5052 extruded bars mount on the side frames with a 10 mm height offset per bar.

How can I confirm the internal volume matches the stated 127 x 158 x 285 mm after assembly?

Measure the finished cavity; it should read 127 mm wide, 158 mm deep and 285 mm high when the top and bottom covers are fitted without the mount bars.
