Fabric components are welded to a Keder
Track that is fed through the ‘C’ Channel on
the Extrusion, guaranteeing a watertight enclosure.
Tension Straps are used on both ends of the
Roof Fabric to assure a smooth and taught surface.


The Pavilion is braced by 10mm Cables with Turnbuckles for both roof and wall sections (see diagrams below). Leg Uprights and Rafters are locked together with the patented Interlock Locking Device. Rafters are secured at the apex with a galvanised Steel Ridge Connector that sleeves both Rafters and is held together with four Gravity Pins. The Pavilion is secured to the ground by 25mm x 800mm Steel Stakes, which
