Mount your monitor onto a 15mm LWS rod with this Offset Swivel Monitor Mount with 15mm Rod Clamp from SHAPE. The mount consists of a 15mm extension rod, a 15mm swivel rod mount, and a monitor bracket with a 1/4"-20 screw.

The mount attaches to a single 15mm rod on your rig, and your monitor mounts using the 1/4"-20 captive screw on the other end. The mount's 8" long rod can rotate to place your monitor into a comfortable viewing position.
