H967 rack
From Computer History Wiki
The H967 rack (officially the H967 Short Heavy Duty Cabinet Frame) was the short version of the H960 cabinet, DEC's standard 19" wide rack (an industry-wide standard width for rack-mounted gear), used with the PDP-8, PDP-11, etc.
The H967 included add-ons such as the rear door, side panels, etc.
It was 4' (49.63") tall, and provided 42" of mounting space. The mounting space in the H967 was divided into 4 10-1/2" units, each of which could be further sub-divided into two 5-1/4" spaces. Most DEC gear (e.g. BA11 mounting boxes) was designed to fit in spaces of these sizes.
H967's often included an 861 Power Controller for line AC distribution and remote control.
