The Catamount Coldframe greenhouse is rugged and easy to install. Simply slip the one piece bow into the ground posts, add your purlin(s) and you are ready to go. These coldframes can withstand heavier snow loads as a result of the purlin being connected to the bow using a cross connector system, as opposed to drilling and bolting a purlin to the bow. The Catamount Coldframes are available in 15’ widths. You can also order extended ground posts for additional height in the greenhouse.
