Which connection relies on the weight of the upper element to hold components together, such as a wall pocket?

Explanation:
Gravity is the force that pulls the upper element downward, creating a steady downward pressure that keeps the components pressed together in a wall pocket. This continuous weight generates the compressive contact needed to hold the joint in place without glue or mechanical locks. Adhesives rely on bonding, interlock relies on matching shapes that lock, and friction depends on surface resistance but isn’t driven by the weight of the upper piece as the primary holding mechanism. In this setup, the weight itself provides the downdraft that keeps everything snug and stable.
