Abstract
A rain gutter joint includes upper and lower clamping members between which adjacent ends of a pair of rain gutter troughs are clamped and joined together. Cooperable pin and socket assemblies in the clamping members enable the members to be fastened with conventional fasteners without exposing such fasteners to standing water in the rain gutter. The joint apparatus accommodates thermal expansion and contraction of the rain gutter troughs and yet also provides a superior watertight seal between the troughs.
