These are our most common sizes of standard window well grates. Typically used for metal wells or metal wells that have had concrete poured around the well such as a sidewalk or patio.
If your basement window well doesn’t match any of the models shown below,
please contact us for alternatives.
Below, select the window well shape and interior size range that matches your window well. The model shown will be the grate your basement window well requires.
All dimensions listed are INSIDE measurements.
Note: These grates are not intended for use on rectangular shaped wells if your well is rectangular – see the Rectangular Grates page. If your well is a precast concrete well with multiple sides, see the grates for precast wells here.
