Aluminum & Galvanized Roof Hatches available in many sizes. Lids are mounted on 12" curb and standard with compression springs, zinc plated steel hardware and insulation in the cover and at the curb perimeter. Smoke hatches are also availalbe.
I really like the products we purchase from Marathon. They are always helpful and much nicer to deal with than my previous manufactures.
