The ultimate in heavy duty performance, VP400 Copystands are ideal for any format camera, still or video, digital or film, whenever a larger baseboard area is required. Eight Nylatron® rollers provide exceptional stability for the camera carriage as it accurately travels the long five foot extruded aluminum column, clearly marked with an easy to read location scale. Fast and precise camera positioning is assured through a rack & pinion drive system enhanced by an adjustable neutral counterbalance for cameras weighing from 6 to 40 pounds. Exclusive dual brake pads offer secure, non-shift braking to lock the carriage in any position along the column. Firm camera support is provided by an oversized dual mount camera mounting plate, secured to four machined steel shafts, sliding on eight bronze bearings for accurate optical centering.
