Ruth's sister Double Ballhead 74mm
The Ruth's sister Double Ballhead is a 74 mm aluminium magic arm designed to mount monitors, lights or small accessories on a camera hot shoe. A single locking knob secures both ball joints simultaneously, giving quick angle adjustment and a firm hold during video work. The compact 2.91 in length keeps the rig lightweight and easy to carry.
Suited for solo shooters adding a field monitor
Videographers who need to attach a single lightweight monitor, smartphone holder or LED panel to a DSLR or mirrorless camera will find the double ballhead simple and secure. Builders requiring multiple accessory mounts, heavy payload capacity or a longer reach should consider a different solution.
74 mm centre-to-centre length decides fit
The fixed 74 mm distance between the two ball centres determines how far the mounted accessory sits from the camera body. Measure your rig to confirm this spacing matches the clearance you need before purchasing.

Questions about this item
Will the single locking knob eventually loosen and need tightening?
The single locking knob is designed to fix the angle tightly and hold accessories solidly, so it should not require regular tightening under normal use.
What stops the arm from flexing when a monitor is mounted at full 74 mm extension?
Non-slip tires on the inner side of each ball joint provide the friction that resists flex once the knob is locked.
Does the aluminium body get hot if a video light runs all day on the end of the arm?
The aluminium alloy construction dissipates heat passively, so the arm itself remains cool even during extended operation.
