R2 VARYX™ - Fully Adjustable Continuous Geared Hinge for Door Repair

For those of us who’ve hung thousands of doors the old-fashioned way, having the flexibility to adjust clearances after the door is hung makes it easier to get it right the first time.


The following article inadvertently omitted several references and footnotes to Austin R. Baer's invention of the ROTON® continuous geared hinge, which is now owned and manufactured exclusively by The Hager Companies of St. Louis, Missouri. In 1990, the ROTON® Corporation was sold to The Hager Companies which has since that time marketed the entire ROTON® Hinge line and has owned the federally registered ROTON® trademark as well as all rights to hinge-related patents filed by Mr. Baer prior to that date. These facts were accidentally omitted from the published article. We regret any confusion that may have resulted from these omissions.

Continuous geared hinges have been around for a long time. What many of us don’t know is that Austin R. Baer, the inventor of the landmark ROTON® Hinge, relied on the maintenance professionals who repaired existing openings to prove that using a continuous geared hinge is the best way to keep a door operating properly and to extend the life of all its other hardware – including locksets, exit devices and closers.

The new R2 VARYX™ Continuous Hinge is Baer’s latest contribution to the door and hardware industry. Because it is fully adjustable vertically and laterally AFTER the door is secured to the frame, VARYX installs in a fraction of the time required with any other repair hinge – without thrubolts.

His patented, centrally-located twist-resistant bearing system and a continuous double interlock boost product strength and performance. In today’s economy, where we’re all looking for ways to demonstrate value to our customers and do more with less in our own businesses, R2’s VARYX™ is the no-compromise choice for the installer who wants to get the job done quickly – and correctly - with the assurance he needs that he’s solved the customer’s problem once and for all.

The hardware industry, asked to solve ever-increasing problems of high traffic, better security and energy conservation, has come to recognize that continuous geared hinges are a cost-effective way to hang a door. Lots of them are in use all over the world… Baer’s ROTON® Corporation put them in our embassies, hospitals, schools, office buildings and even the White House.

What many people don’t realize is that it was the locksmith profession, joined by building and maintenance managers - the people who have to repair these openings and keep doors swinging – that made it all happen. The overwhelming response from the “repair/retrofit” side of the industry convinced architects to specify these products for new construction.

Recently, Baer joined forces with his daughter, Kerry B. Sprick, to found R2 HINGE®. Their flagship product is the all-new VARYX™ Continuous Hinge for door repair, a heavy duty, full-surface model that can be used on standard hollow metal or narrow-faced frames and with doors of any material. VARYX stands for “VARiable position in the Y or X axis”…remember your high school geometry?

Here’s what’s new and different with R2’s VARYX™:

One man can hang a door in under 20 minutes after the old hardware is stripped…and get the clearances right on the first try. Because the door is never fully removed from the opening, it’s a lot safer and easier to re-hang. Instead of hinges that require the door to be measured, shimmed, measured, marked, prepped and drilled for thrubolts - all the while never really knowing whether it will fit back into its often beat-up frame after all those preparations are done – VARYX is applied immediately.
