Tired of butterfly shutter maintenance? Butterfly shutters stick open, springs periodically have to be replaced, and they can be very noisy when subject to wind pressure. New Butterfly conversion kit is an easy way to eliminate a butterfly shutter and replace with a new Eco Tight Shutter. The patented Eco Tight Shutter operates very quietly with minimal noise, does not require any spring maintenance, and shutter performance is minimally affected by the wind.
Some of the fan housings for butterfly shutters will not allow a direct shutter replacement, when the shutter blades open there isn’t enough clearance & blades can hit the fan motor. This new shutter conversion kit is designed to add tolerance so the shutter blades will not interfere with the motor.
