Ring-joint blind
A ring-joint blind is a blocking component intended for a joint using ring-joint geometry and must match the mating faces and grooves of that connection. The title does not fully define whether its body follows a paddle or ring-blank form, but it establishes the grooved-joint context. Ring number, groove dimensions, class, material, thickness and standards basis require separate confirmation.
Application and duty
