    Key Features

    • Bi-folds run on rollers at the sill ensuring they don’t pull the door lintel down and therefore they work smoothly over the long haul. Top clearance allows up to 6mm of lintel movement.
    • Series 548 Bi-fold transom has a narrow profile. This allows a designer to include 2100mm-high doors plus an overlight in a standard 2400mm-high opening. (Opening sashes as well as fixed overlights are available).
    • Very deep water ‘head’ at the bottom. The bigger this measurement – from drainage hole to the inside leg – the more assured the water drainage in wet or stormy conditions.
    • The Vantage Series 548 High Performance Bi-fold door features an unusual design embellishment – extra wide top and bottom rails that give the door the chunky appearance of traditional timber designs.
    • The centre hinge between door panels has a built-in handle to allow the home owner to easily pull the panels back into the closed position.
    • Series 548 Bi-fold door can be fitted with Centor S1 retractable screen.
