MPR Rails — 180mm / 7.1"
Versatile multi-purpose rail for demanding support setups
The Really Right Stuff MPR accessory bars give you a wide range of options for mounting cameras, optics, and accessories in support setups that need flexibility without giving up rigidity. Like our traditional camera bars, both the top and bottom surfaces use the 1.5" RRS dovetail standard for compatibility with all RRS quick-release clamps, while alternating 1/4"-20 and 3/8"-16 threaded sockets spaced 15 mm apart across the top and bottom create flexible mounting points along the rail. The sides of the MPR rail add 1/4"-20 threaded sockets spaced 9 mm apart, making it easier to attach accessories, brackets, or secondary hardware without interfering with the primary clamp surface. Its extruded 6061-T6 aluminum profile is designed to be 14% lighter per inch while remaining 25% stiffer than our traditional camera bars, and the laser-engraved 5 mm markings make repeatable setups faster in the field or studio. The MPR rail system is available in 180 mm, 270 mm, 360 mm, and 450 mm lengths, giving you scalable options for everything from compact support builds to larger multi-accessory rigs.
