TPI double elevator column tripod features aluminum construction with a two-tier telescoping and adjustable elevator column built-in. The bottom half of the column is gear driven, and cranks up or down for fast or fine adjustment. The top half of the column allows greater elevation by hand using a quick-release clamping mechanism. Tension knobs and a removable rotating top plate allows you to attach and align your instrument while holding your settings in place.   It features a built-in circular vial in the instrument head, quick clamp legs, and black hardware. Safety chains on the legs prevent slipping on hard surfaces.
