SELECT
Hinges Sets Record; Reaches 25 Million in Cycle Testing
A SELECT aluminum geared continuous hinge celebrated its silver
anniversary - achieving 25 million open/close cycles in independent
testing.
"We're proud that our hinge has reached this landmark level
of performance," said Bob Cronk, SELECT vice president, sales
and marketing. "We're not aware of any other independent test
that has put a hinge through this many cycles. We believe this is
a record."
According
to the company, the hinge has withstood continuous, nonstop cycle
testing for more than four years without fail at Architectural Testing
Inc. in St. Paul, Minn., where SELECT's full mortise aluminum SL11-HD
geared hinge was mounted to a standard FRP door to simulate a real-world
situation. A piston initiated the door's open/close cycle 16,600
times per day, around the clock. On a real-world school entrance
averaging 400,000 cycles per year, this equals 62 years of high-traffic
use.
Pair-Matched hinge leaves are manufactured, machined and anodized
together with paired serial numbers s. Anodizing after machining
creates a smoother surface for bearings to move against, decreasing
wear and lifetime lubrication delivers maintenance-free performance.
"Our unique manufacturing processes work together to achieve
this durability," Cronk said. "Proving our aluminum geared
continuous hinge will last for more than 60 years of heavy use gave
us the confidence to offer the industry's only Continuous Warranty.
SELECT's Continuous Warranty covers any failure of its geared hinges
with no expiration date, if they were properly installed.
