Limits the accumulation of snow, leaves and debris. Constructed of
polycarbonate, this high impact cover is UV-resistant and designed
for durability and long life.
Note: For applications with a casement window, the well must be
installed so that it is above the top of the window for a dome cover
to be utilized.

Selecting the Proper Size
Step 1:
Measure or calculate dimension A as shown in the detail
on the right based on the site’s grade conditions and
foundation height.
Step 2:
Determine the required window well side panel height by
performing this simple calculation:
Required Side Panel Height = Dimension A + 7 ½”
From the table below, select the closest height that
will meet the site conditions.
Step 3:
Once the side panel height has been determined, read
across and select the desired window width. With the
window size selected, read across to select the proper
window well and cover.
Note: Both StakWEL

and ScapeWEL
