CINCINNATI, Ohio—Hollaender® Manufacturing  has received UL 2703 Recognized Component Approval under Intertek ETL mark No. 5006508 for its Speed-Rail® brand solar pipe rack fittings. The Speed-Rail slip-on pipe fittings are used with aluminum or galvanized steel to easily and cost-effectively build solar panel racking systems.

UL 2703 is a solar industry standard that covers rack mounting systems; mounting, grounding, and bonding components; and clamping and retention devices for specific flat-plate photovoltaic (PV) modules and panels that comply with the Standard for Flat-Plate Photovoltaic Modules and Panels.

Hollaender said in a press release that Intertek conducted thorough and rigorous testing, which showed that specific Speed-Rail fittings form a safe and reliable bond with assured electrical continuity. A proprietary set screw developed by Hollaender is used to secure the fitting to the pipe, and penetrates the surface of the pipe. When properly installed, the set screws are electrically bonded to the pipe and bracing, thereby fulfilling the grounding and bonding requirements of UL 2703. Testing was done with both galvanized steel and aluminum pipe.

Hollaender’s Speed-Rail fittings, made of 535.0 aluminum-magnesium, are reported to be strong, lightweight fittings that are highly corrosion-resistant. They come in a wide variety of fixed and adjustable configurations, including the tees and flanges most commonly used in solar panel installations. They are backed by a 10-year warranty against corrosion and can be used with galvanized steel or other metals without concern for galvanic corrosion, the company said.

Hollaender ( is a manufacturer of aluminum structural pipe fittings, aluminum pipe, and final assemblies that use these components. Hollaender components are used in the design and build of handrail, guardrail, and safety rail systems, as well as a wide variety of unique modular pipe and fitting-based structures for commercial, residential, public works, and industrial applications. They are also used for retail store fixtures and other structural applications. The company also designs and manufactures complete architectural railing systems, often called “decorative metal railing systems.”
