BUTTERFLY CONVERSION KIT DIRECTLY REPLACES
OLD BUTTERFLY SHUTTER WITH PATENTED ECO TIGHT SHUTTER.
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.
