Overview

When installed, the Bulbtite body folds into three legs, forming a large bearing surface on the blind side. It gives high clamp force in soft, thin or brittle materials and high pull-through resistance.

An EPDM washer under the head makes the joint waterproof, and the wide grip range means one rivet covers many thicknesses.
