The speed rail offers these great benefits over conventional mounting systems:

  • Flexible design to allow various configuration including horizontal and vertical mounting
  • Fully adjustable X and Y axis to ensure homeowners see only perfectly aligned rows of panels
  • Lightweight aluminium in a low profile for a clean and easy installation
