Extron PMK 155 (part number 70-739-12) — a black low profile pole mount kit that hangs a half-, quarter- or eighth-rack device and its power supply from a projector pole.

Extron built the PMK 155 for the tight space between a suspended projector and the ceiling, where a full rack shelf will not fit. A steel plate clamps to a round pole or pipe with an outer diameter of 1.85 to 1.95 inches, and the device bolts to the plate while its external power supply is tie-wrapped underneath, out of the sightline. Extron's own installation guide lists what fits: one 3-inch-deep half-rack device, one 6-inch-deep half-rack device, two 3-inch-deep quarter-rack devices, four 4.5-inch-deep eighth-rack devices, or a single MPA 401 amplifier, all within a 5 lb (2.3 kg) limit.
