Hanwha Swivel based Telescopic Ceiling Mount, White (special order)

The “special order” telescopic ceiling mount you are referring to is most likely the SBP-302CMASW (or the SBP-300CMTW / SBP-156CMW depending on the specific camera model). These are designed for high-ceiling environments like warehouses, airports, or big-box retail where a camera needs to be lowered to a specific height and potentially adjusted for a sloped ceiling.

The term “Swivel-based” typically refers to the swivel adapter at the top of the mount, which allows the pole to hang straight down even if the ceiling is angled (up to roughly 45° to 90° depending on the specific joint).
