Hollaender has introduced two new Speed-Rail fittings, designed specifically for installation of solar racking systems in areas that experience extreme wind. The fittings include a tee and elbow for use with two-inch IPS pipe. The ability to withstand uplift caused by wind loads is critical in solar pipe racks. Though most regions of the US must design for 90 mph winds, certain coastal areas (such as South Florida) and the Gulf Coast must design for 135 mph and higher wind speeds.
On a Speed-Rail fitting, the component that produces pipe-holding power is a single, integrated proprietary internal/external reverse-knurl, cup-point set screw, which securely attaches the fittings to the pipe, and provides tremendous resistance to loosening and pullout. The new fittings are designed with two set screws, producing a substantial increase in pullout resistance.
Speed-Rail slip-on pipe fittings are used with aluminum, galvanized steel, stainless steel, or black iron pipe to easily and cost-effectively build solar panel racking systems. They come in a variety of fixed and adjustable configurations, including the tees and flanges most commonly used in solar panel installations.
