Not since the introduction of Rubbair's original flexible door has the industry seen a product that offers such a quantum leap ahead of existing door designs. Quantum doors provide a one-two punch of advanced hardware and molding technology that delivers more resistance to impact, superior long lasting hinges, corrosion resistant hardware, wider two-way swing, excellent sound and thermal insulation, plus easy installation and minimum upkeep.

Smooth, Low-Wearing Helix Cam Hinge - Simply Better

The unique geometry of the helix gives Quantum a huge advantage over more complicated designs and requires no oil, grease, bearings or bushings.

An upper hinge section of precision machined aluminum travels upon a lower cam section milled from wear resistant high-strength polymer. Both sections share a common helical wear surface. As the door opens, load and friction are spread evenly across the entire helix surface... there are no points or edges to concentrate wear

Easy To Install - Easy to Maintain

Quantum doors are shipped with a mounting template to assure precision positioning of the hinge bracket and lower bearing. The door simply drops into the bearing and slides into a slot on the mounting bracket. Three screws secure the helix hinge to the bracket. Tapped holes assure correct alignment. Height adjustment can be easily made by rotating the upper helix section in 360° stops.

Easy, Reliable Installation Procedures.
