Fan Hinging Solutions
Quick Fit Super Hinge
The patented Quick Fit Super Hinge™ offers easy access to rooftop up-blast exhaust fans and is available in standard or custom sizes, fitting fan bases from 10 to 45 square inches. This unique mounting system, specific to the QF Super Hinge™ models, features a tab-based upper arm that allows for installation while the fan is running and supports single-user installations (depending on fan weight or foundation condition).
