KnuckleHead Roof Pipe Supports by GreenLink

Pipe Stands & Supports

Duro-Last® offers the KnuckleHead Rooftop Support System by GreenLink Eco-Engineering as a solution for your rooftop support needs. KnuckleHeads are tough, molded fiberglass-reinforced nylon rooftop supports designed to keep equipment elevated to extend your roof’s life and protect your investment. KnuckleHeads are height adjustable, can support up to 600 lbs. each, and have undergone 10 years of exposure in the field without showing signs of weathering or deterioration.

Five KnuckleHead designs are available from GreenLink, depending on the application. Regardless of the design, all KnuckleHeads utilize the same Universal Base and install using the same basic steps. They can be loose laid, bonded using an approved Duro-Last caulk or an approved Duro-Last caulk combined with mechanical fasteners.

Additionally, KnuckleHead Extension Pipes are available for elevated installations, and can be used in conjunction with a Duro-Last membrane stack flashing.
