Pinnacle System

For spectacular large-scale custom structures spanning up to 40 feet, at any pitch you desire between 15° and 60°.

With its variable-pitch hinge design, the Pinnacle Systems offer you the versatility of a custom configured structural skylight system with the reliability and cost savings of standardized engineering, construction and installation. Fast on-site assembly and installation. Spans up to 40 feet, at any pitch you desire between 15° and 60°.

  • Built to order from stock for shorter lead times
  • Fewer parts, faster on-site assembly
  • Narrow profiles provide clean lines
  • Larger span capability
  • Available in Hurricane Resistant

Quicker Installation
Components always assemble the same consistent way. Sills encompass the entire perimeter so installers rely less on sealants.

Continuous sill enclosure around skylight perimeter helps reduce air infiltration through weep holes and effectively guards against water intrusion. Thermally-enhanced construction.

Concealed Fasteners
Through bolt fastening system further eases installation, providing a clean, aesthetically pleasing look on both the interior and exterior.
