Door Closers & Door Holders - Heavy Duty
Example: Door Closers Capable of 10 Million Full Load Cycles -
More than any other, the 4000 series heavy duty closer cylinder is the mechanism upon which our reputation is built. Closers incorporating this cylinder are controlling doors in many of the worst possible situations worldwide and they do so for incredible numbers of operating cycles without maintenance or adjustment. This continuing unsurpassed performance in real world situations demonstrates the excellence of the engineering far more conclusively than even the almost incredible results of the recently updated, independently monitored, 10 million full load cycles test.
