Rack-Mount Chassis: About


London Power now offers chassis to house your projects!

These rack-mount chassis are manufactured in Canada by Hammond, and come as "knock down" pieces that bolt together with four screws per panel. The rack mounting ears can be left off if the unit is to sit on a shelf instead of being mounted in an equipment rack. The external components are thick aluminum, with four steel corner inserts for support and attachment of the panels to each other.

Aluminum is easy to drill and cut holes into, so it is a perfect choice for hobbyists and amp builders requiring a cost-effective and versatile chassis choice.

1U rack-mount chassis

The top, bottom, sides and rack ears are finished in black textured semi-gloss powder-coat paint. Top and bottom panels are interchangeable and are ventilated. The front and rear are also interchangeable, one having smooth black paint and the other having smooth white paint.

The manufacturer produces six chassis heights, from 1U to 6U (we currently offer 1U to 4U), and three chassis depths (front to back). The standard depth is 13" (330mm), but the 1U and 2U are available in a shallower depth of 8" (203mm), and 6U is available as 15" deep (381mm). The 1U to 4U range is the most useful to hobbyists and small builders, but contact us if you are interested in the 5U or 6U chassis.

We also carry "chassis insert panels". These bolt to the side panels inside the chassis and are shallower in depth than the chassis box. The insert has a "U" cross-section that mounts upside-down. Everything inside the chassis can bolt to the insert, leaving a clean exterior panel finish. This panel should be used with chassis larger than 3U and larger, or where internal height constraints are not an issue as the insert effectively raises the floor of the chassis by approximately 0.5" (13mm).
