Typical Hollaender® Rail Installation

Hollaender Interna-Rail

The Interna-Rail system by Hollaender is a beautiful way to easily fit pipes together while maintaining a clean, sleek look to your railing system. The Interna-Rail uses a tubular rivet that is inserted into the pipe after drilling the initial hole. A header tool is then used to crimp the rivet around the inner edge of the tube, holding it in place. Hollaender pipe fittings can then be secured to the pipe using a socket head cap screw.
