Door Assembly/Installation
Door Assembly/Installation
To install the Door in the Cone you must first identify the top of the Cone and the top of the Door. The
bottom of the Cone Has a C-shaped cut-out in it that will later be used for a drainage knockout (See Figure
8). The top of the Door can be identified by the location of the Door Springs. The Spring attaches to the Post
towards the top of the Door (See Figure 8). With the Door opening towards the ground, as shown below,
line up the Four Holes in the Door Ring with the second set of holes from the edge of the Cone and thread
(4) 5/16 x 1.25" Bolts in until they are tight. Do not install Nuts at this time. These Bolts will be used later
to attach the Cone Brackets.
Second Set of Holes
from Edge of Cone
Use (2) 5/16 x 1.25" Bolts and 5/16 Flange Nuts to attach the Ring to the Cone using the Holes located on
both sides near the Door Center Brace as shown below. Note that the Nuts go on the outside of the Cone.
Turn the Cone over to install the Grill. Orient the Grill so the Leg with the bent spokes at the Center of the
Grill is Parallel with the Center Door Hinge and that the bent Spokes are either above or below center. Not
to the left or right. (See Figure 10). Install the Rubber Grommet 3/4" to 1" from the end of the bent Spokes.
Fasten the Grill on with (8) 5/16 x 1/2" Carriage Bolts and Flange Nuts as shown below. Note that the Nuts
are to the Inside of the Cone.
