The QRail® Series is an innovative rooftop racking system featuring QClick® and QSplice® technology that simplifies and speeds installation. QRail® seamlessly combines with QuickMount® waterproof mounts to provide a complete, fully integrated racking and mounting solution for installing solar PV modules on any roof.
QClick® and QSplice® technologies make installation fast and easy. Electrical bonding is fully integrated into every system component. QRail® also comes with QDesign®, a free online tool to enable quick and easy design of solar array configurations, generate complete engineering reports and calculate a precise bill of material for all the mounting, racking and accessories needed for a complete solar array. QRail® is available in aluminum mill and black finishes.
QClick Technology®
The universal mid and end clamps use QClick® technology to simply “click” into the rail channel and remain upright, ready to accept the module. The pre-assembled clamps fit virtually all module frames and require no extra hardware, eliminating pre-loading and reducing installation time. Once installed, the clamps easily slide in the channel for fine-tuning module placement.
QSplice® Technology
QRail® innovative internal QSplice® installs flush in seconds, requiring no tools or screws. Simply insert QSplice® into the rail and slide the other rail on to create a fully structural, bonded splice.
Fully Integrated Electrical Bonding
The QRail® system provides an integrated electrical bonding path, ensuring that all exposed metal parts and the solar module frames are electrically connected. All electrical bonds are created when the components are installed and tightened down.
Comprehensive, One-Source Solution
QRail®, together with QuickMount® waterproof mounting products, provides the benefit of a single-sourced, seamlessly integrated rooftop installation that works with all roof types — composition/asphalt shingles, flat or curved tile, metal shingle, shake, slate and low slope roofs. The QRail® system also works with any roof attachment system for maximum flexibility.
Superior Strength & Versatility
QRail® is engineered for optimal structural performance. The system is certified to UL 2703, is fully code compliant and backed by a 25-year warranty. QRail® is available in Light and Standard versions to match all geographic locations. QRail® is compatible with virtually all modules and works on a range of pitched roof surfaces. Solar modules can be mounted in portrait or landscape orientation in standard or shared-rail configurations.
