Original Press Release:

Hollaender® Manufacturing Develops New "X Series" Pipe Fitting Designed to Deliver Superior Pullout Strength

CINCINNATI, OH – After extensive pullout strength testing of the Hollaender® Speed Rail® slip-on aluminum pipe fittings, Hollaender Manufacturing has developed a new line of “X series” fittings that increases pullout capacity by 60% over the single set screw designs and 40% over the current two set screw (in line) designs. The added pullout strength adds increased security and durability to a wide variety of solar panel installations.

Hollaender discovered during their testing that the Rockwell hardness of the galvanized steel pipe commonly used in the solar industry varied by 30-40% over the length of the pipe. Surface hardness directly affects the set screw pullout force, and with the discovery of the hardness variations Hollaender has restated their pullout values to be more accurate, resulting in the development of the “X series” which will withstand much higher pullout forces.

The new Hollaender® Speed-Rail® “X Series” design incorporates a second set screw set at 90 degrees in the vertical barrel to achieve the increase in pullout strength. These new fittings have the same list price as the standard one set screw fittings and provide a vast increase in pullout strength. The “X Series” is now available in Hollaender’s most popular fixed and adjustable tee fittings.

Hollaender® 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 are strong and lightweight, and come in a wide variety of fixed and adjustable configurations, including the tees and flanges most commonly used in solar panel installations. The versatility of the fittings allows dependable support structures to be constructed virtually anywhere a solar panel needs to be installed. The same versatility also allows the systems to be easily uninstalled and moved if necessary. They are backed by a 10-year warranty against corrosion, will not rust, and can be used with galvanized steel or other metals without concern for galvanic corrosion.
