With a 26-lb. lifting capacity, twice that of standard solar openers, the Mega Vent is the best choice for heavier roof vents, side windows, and skylights.
A built-in hydraulic damper prevents the vent from being opened by high winds. An extra-strong return spring provides positive closing action. The cylinder can be adjusted for opening temperatures between 63 -77 F. Fully open at 15". 2-year mfg. warranty. Aluminum finish. Made in Denmark by J. Orbesen Teknik.
