It is important to use a frame that is supported underneath the frame flange entirely by the ground or other structure supported by the ground (like the leftmost photo). Do not put a frame with a clear opening that is smaller than the hole opening - overhanging air - like right-side photo. With a smaller clear opening frame than hole, your assembly will not be fully supported.
Use a weather and corrosion resistant adhesive sealant between the frame flange bottom and the surface below. Though this is not an endorsement of specific sealant, some examples commonly used are shown in the picture to the right.
Avoid using a small piece of wood, rock, metal (etc.) as a "shim" to angle the cover to grade. Some riser rings are made so that you can create the grade angle with complete frame support. Always follow the riser ring manufacturer's instructions to achieve the proper angle.
The information that follows is intended for general informational purposes only and does not necessarily represent appropriate advice for your specific application as each individual application has its own variables, such as climate, temperature, soil type, chemical exposure concentrations, grade, and other factors therefore be certain to consult with your contractor, engineer, and other required professionals for your specific application.
To anchor the frame to the ground, CAP's frames have molded in anchor holes. Anchor a threaded rod into the ground using anchor bolts following the manufacturer's instructions. Align the rods to enter the frame holes, and place the frame on the rods. Cut to size and fasten the frame to the rods. This photo shows one possible anchor bolt product and is not an endorsement.
Make absolutely sure to wipe and clear materials from the inside of the frame wall and built in notches. When using a quarter-turn paddle lock fastener, these frame notches are used to engage the latch. Blocked with debris, the cover might not lock to the frame.
Some installers prefer a square of concrete around the frame and some a circle. Some also use rebar, create expansion joints or other techniques.
Some installers recommend 5000 psi concrete a minimum of 12 inches from the frame edge, at least 6 inches deep, using #4 rebar 12 inches on center. Allow 24 hours for concrete to cure before allowing traffic contact (refer to concrete mix instructions).
You may need to rotate the cover if the holes and hardware do not line up. The frame has shapes (triangles, stars) that indicate where the bolt holes should be aligned to have the cover and frame holes centered on each other.
Paddle locks need to be pressed down and then rotated to engage the frame. A mark on the head of the paddle will point away from the cover center and toward the frame wall when the latch is locked. This mark is in the same direction as the paddle underneath to cover.
CAPs come with rubber plugs intended to help keep fastener areas clean.
Clean cover surfaces of excess asphalt. If left to dry, covers will be difficult to clean later.
People do notice how manhole covers are installed. What does it say about your city?
