Although we've reviewed recessed can covers before in the past, CanCoverIt is different in that it ships flat, pops open without any assembly, and is easily cut to fit around brackets, wiring, and framing. Simply press it onto the can light’s brackets to make indentations, cut along the indentations, then push the cover firmly in place and stuff insulation around it. If desired, foil tape can be used to seal around the base. Price: $16 standard cover; $13.50 low-profile version. EcoCycleSolutions, 949.275.4861, cancoverit.com
