Compatible with 15mm LWS rod systems, this Universal Adjustable-Height Long Lens Support with black knobs from Niceyrig fits LWS rods with a spacing of approximately 2.4" center-to-center. The lens support helps carry the weight of lenses with a diameter of 50 to 140mm. There are two integrated rubber grips on the Y-shaped lens support for eliminating vibration and preventing scratches. Two 3/8"-16 and two 1/4"-20 threaded holes allow you to mount accessories such as articulating arms for lens lights, French flags, or other accessories. You can adjust the height of the support to accommodate different lenses via a thumbscrew.
