The 400 Series of video endocouplers features a large knob for simple adjustable focus and a clip quick-release mechanism. Weighing less than 80 gm, the coupler's streamlined design allows a profile that is slightly larger than the endoscope eyepiece. The clip quick-release mechanism provides a tight, centered fit when desired, so the endoscope stays where it is placed, yet allows rotation within the eyepiece.
