This unique solar vent control will open and close roof vents, a cold frame lid, top-hinged wall vents, or even the greenhouse door. It features two closing springs for extra strength. The Univent solar vent opener is the only solar-powered control with a quick-release mounting bracket. Just grasp the “clutch” arm and squeeze for easy detachment. This allows a cold frame lid to be fully opened for access to the plants.

The solar-powered cylinder can be adjusted in 1° F increments for opening temperatures between 60° F and 77° F. Full opening of 18" is reached at 86° F. Lifting capacity is 15 lbs. Installation is simple using the mounting clamps for aluminum vents, or screw directly to a wooden frame-work. Materials are corrosion-resistant aluminum and stainless steel.
