This is a window mount that holds the (usually quick release) baseplate used for a camera to mount on a tripod. It uses the window's sash lock/latch to anchor itself by having the short panel of the camera mount positioned behind the latch. This is achieved by sliding the camera mount from either side of the window lock.

This requires no screws, clamps, or moving or interlocking parts, and relies strictly on the geometry and configuration of the window lock
