Hart and Cooley LLC brings over 105 years of experience in the manufacturing of a broad range of products.
Easy Complete Opening: Hart and Cooley LLC hatch covers open easily to 90 degrees. Operation is assisted by enclosed torsion bar or torsion coil spring operators. Automatic hold-open arms keep doors securely open.
Unobstructed Opening: The clear hatch opening is virtually unobstructed, with only a narrow hold-open arm at one corner and the torsion bar or spring mounted out of the way in the cover or frame.
Complete Seal: Heavy, closed cell, rubber gaskets factory-applied to the units provide a barrier to weather penetration and drafts. Latching devices with inside and outside handles hold hatches tightly closed.
