Reinforced rain gutter doors seal around topside opening to prevent leakage or moisture. Heavy-duty hinges provide high strength security and longevity. Stainless steel rotating T-handle pulls the door tight against the seal. Quick release coated aircraft cables allow door to drop down 180° for full accessibility. Automotive bulb weather stripping seals door 360°. Tough Armor-Brite® powder paint finish has superior rust resistance.
