Heavy Duty Twin Camera Slide Bars (18" -- 28")

Heavy Duty Slide Bar (Full) Heavy Duty Slide Bar (Detail)

This series of Slide Bars were designed for use with most cameras and especially for larger SLR's and Medium Format cameras.

The Heavy Duty Twin Camera Slide Bars (HDSLB's) can be used with one or two Roller Blocks, for single still life or twin camera live action stereo photography. The Bar has Engraved Lines for the Block center alignment and lines 1" (31.75 mm) each side of the Block position, to be used as reference points to set the Adjustable Sliding Stops at your desired spacing. The Blocks and moveable Sliding Stops are removable for camera mounting. They are also equipped with soft tipped Thumb Screw Locks for steady action. A Bubble Level is inset into the Bar and the Bar is equipped with spring loaded Safety Button Stops on each end so that your camera won't accidentally roll off the Bar. The Bars also make a great focusing rail for macro photography.

The Heavy Duty Slide Bars are 18", 28" total travel between the Safety Button Stops.

The Roller Blocks are 2" Wide x 3" long or 1.5 " to the center line of your lens.
