REDTiP ExpressRail Connector Joins two ExpressRail lengths together, the perfect partner for REDTiP roof hooks for tiled roofs. REDTiP Rail Ranges are simple yet brilliant; ExpressRail for tiled roofs & SwiftRail for Profiled Sheet roofs. They’re both simple to install and transport with tough, universal wrap around jointing plates and easy assembly module clamps, giving an elegant finish to any PV array. Supplied in convenient lengths they’re easy to transport and with no ‘special’ parts, that add cost to other mounting systems, there’s also less to clutter up your stores.
