Quantum Impact Door

Not since the introduction of RubbAir's original flexible door has the industry seen a product that offers such as 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 minimal upkeep.

Smooth, Low-Wearing Helix Cam Hinge

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 helix surface... there are no points or edges to concentrate wear. The result is a smooth ride for the door. Even with bumpers installed, Quantum allows up to 125° of swing both ways to provide clearance without overextending the hinge. As the door closes, it automatically drops back into the closed position.

	The aluminum upper helix hinge section "climbs" the dark polymer cam section to swing and raise the door without pressure points or edges.
	While rotating, about half the total helical surfaces remain in contact to spread the load and reduce wear.
	125° swing geometry permits greater clearance in both directions.

Advanced Panel Design and Construction

RubbAir employs proprietary molding techniques to form a tough monolithic polyethylene door "shell" that resists penetration by moisture, dirt or cleaning agents. The structural composition of these doors resists impact, bending and torque like no other. Beginning at the door's center with a wall thickness 50% greater than competitive door panels, the shell wall progressively increases to resist breakdown or fatigue around load bearing areas. The entire door is injected with urethane foam for rigid structural characteristics. A steel tube encased in the foam adds additional strength and stability along the spine where it's needed most to prevent warping, breaking or binding at hinge or bearing points.

Standard Features

One piece molded body resists penetration by moisture, dust or chemicals.
50% more shell thickness at impact areas than comparable doors.
Helix hinge allows for up to 125° swing in both directions.
Industrial-grade steel bracing the length of the door's spine.
Rugged polyethylene shell resists impact and bearing.
Factory aligned hinge.
1-3/4" door thickness with foam fill for sound and thermal insulation.

	Stainless hinge post is securely bolted to the door's spine.
	Cross section reveals extra shell thickness at impact areas.
	Nylon reinforced vinyl gaskets slide easily into molded channels to form a seal against air flow and dust.
