Instructions
STEP 1: Create The Tracing
STEP 2: Adjust The Grate On The Tracing
Use the flat piece of cardboard supplied and lay it over
your window well. Position the cardboard up to the
house and have one person press it firmly against the
top rim of well while another person in the well traces the
inner contour on the underside of the cardboard.
We recommend a pencil so that it can easily fit between
the cardboard and the lip of the well to give you an
accurate representation of the edge of the well. Pens
don’t typically work upside down and thick markers
cannot get close enough to the lip of the well to create a
A) Lay your cardboard tracing on a flat sturdy
surface (not a soft or uneven surface like lawn or
rocky areas) enabling you to properly tighten the
grate later.
NEVER attempt to adjust the grate
on the well itself.
B) Place the grate on the top of the tracing with
the bottom side of the grate facing up (bolt heads
down). Be sure the front of the grate, as marked, is
facing front (curved side) of tracing.
C) Position the grate on the cardboard with a space
between the front line of the well and the grate,
approximately 1
½ inches. This space is nearly equal
to the spacing already present in the grate and will
make it easier to adjust the front brackets in a later
step. The space between the grate and the back
edge of cardboard (representing the house) will
vary, however, ensure there is a minimum of
1/8 inch
here to insure the grate will fit into the well after
adjustment. If you have a tight fitting grate, you
may need to lessen the gap at the front of the grate
slightly. (See Figure 1)
D) Loosen all nuts about 1 full turn.
E) Slide the front set of loops even with the traced
line, this prevents the grate from sliding forward
in the well. Then, slide all remaining loops to...
true representation of the well.
Important Note: If you have more than one grate to install, a separate tracing for each well is necessary due
to irregularities in shape of well caused by installation and backfilling. Precast concrete wells may also require
individual tracings, however you can make one tracing and then try the adjusted grate on another well to check for
fit prior to making additional tracings.
Note For Small Wells:
Create the tracing by using the heel of your hand or a rubber mallet to press along the lip of
the well, creating an indentation of the well shape onto the underside of cardboard.
