Cover: 1/4-inch (6.4mm) aluminum diamond plate cover reinforced for occasional, off-street AASHTO H20-44 traffic loading—capable of holding 25 feet of head water. Equipped with 9/16-inch (14mm) diameter EPDM gasket around perimeter, flush floodtight lifting handle and 316 stainless steel hold-open arm with red vinyl grip that automatically keeps the cover in its open/upright position. (Upon request, manufacturer shall provide structural calculations showing that the door design meets the loading requirements of AASHTO H2-44.)
Lift Assist: Open stainless steel horizontal springs for easy opening
Frame: 3/8-inch (10mm) aluminum angle with 3/16” x 1 1/2” (5mm x 38mm) strap anchors spaced around the frame perimeter. Bituminous coating on frame surface in contact with concrete.
Hardware: 316 stainless steel hinges and tamper resistant bolts/lock nuts.
Security: 316 stainless steel cam locks compress the gasket so the door will not leak.
Finish: Aluminum cover and frame have mill finish which is protected during shipping and installation by an attached adhesive-backed vinyl material.
Installation: Installation shall be in accordance with the manufacturer’s instructions. The entire frame, including the seat on which the reinforcing rests, shall be supported by concrete or other material designed to support the specified loading.
Warranty: Manufacturer shall guarantee against defects in materials and workmanship for a period of ten years.
