Installation Tips

Ensure Adequate Frame Clear-Opening Diameter: Larger than for Hole Diameter

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.

Sealants

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.

Achieving Grade

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.

Anchors

 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.

Important: Clean Mortar, Concrete, Debris

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.

Concrete Collar

 Some installers prefer a square of concrete around the frame and some a circle. Some also use rebar, create expansion joints or other techniques.  

image9

Don't Cut Corners!

 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).

Bolted CAPs: Align Bolt Holes to Frame Indicators

 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.  

image11

Paddle Lock CAPs: Push and Turn Notch to Outside

 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.
