Rotons solve and prevent problems
| Continuous Integrity |
 |
| This continuous hinge extends the full length of the door and frame. Instead of a pin, typical of traditional hinges, it uses two centers to form a rotating joint. Since the two centers roll when they come in contact, lateral wear is minimized. The unique gear profile extends from top to bottom inside a high-strength cover channel. The door weight is supported and cushioned by molded Lubriloy™ RL bearings evenly spaced along the entire length of the interlocking leaves. In a sense, the Roton hinge physically bonds the door and frame together.
|
| Roton Reduces Stress |
| Typically, traditional hardware is under-specified or poorly installed due to misaligned cut-outs. With butts and pivots, door weight and stress are localized. The resulting twisting causes distortion and uneven wear. Roton evenly distributes the door weight. |
 |
How Something So Straight Can Be So Flexible |
| When Roton is used in retrofit projects, it can actually "rehabilitate" a warped frame or misaligned door. But its ability to correct problems does not limit its flexibility at the job site; in fact, no door or frame preparation is required. Doors can be reversed in hand or in swing. Unused mortise cut-outs are covered by the full length of the hinge leaves. |
 |
Still Swinging After All These Years. |
| Roton actually extends the life of an opening and reduces replacement and maintenance costs. Typical problems such as door bind and sag are eliminated. Each leaf and cover channel is made of hard extrusion alloys (6063-T6 Aluminum) to minimize friction and wear. Bearing units are molded from Lubriloy™ RL, an engineered nylon, to ensure hard, durable, resilient, and uniformly shaped bearings. Roton is low-temperature and corrosion resistant, perfect for swimming pool buildings, sewage and water treatment plants, salt spray environments and freezing conditions. Even the heaviest doors are easier to open. |
|
Security
Because Roton eliminates the gap between the door and frame, doors can't be pried open or removed. This makes for a secure seal, useful in high-security applications. |
|
Energy Savings
The amount of energy lost through the typical hinge-side gap equals the energy lost through a 3" square hole. Roton provides a continuous and permanent weather barrier. |
|
Privacy
Roton conceals gaps typically left when doors are open. When privacy is needed, as in public restrooms, Roton is the perfect cover-up. |
|
Warp Resistance
Roton hinges may help eliminate the warping of wood or laminate doors |
|
Sound Retardation
By eliminating the gap between the hinge and the door, Roton helps reduce noise transmission. |
|
Safety
Various models of the Roton hinge will help prevent pinched fingers. These models are specifically designed for use with stopless frames to allow doors to close with little fear of injury. |
|
Appearance
The continuous cover channel provides an award-winning design and aesthetically pleasing appearance. |
