Grates for Precast Concrete Wells

These are our most common sizes of precast window well grates. Used for precast concrete wells with multiple sides.

How to select the right pre-cast concrete model window well grate:

Step 1:

Measure your window well. Use inside dimensions only as Adjust-A-Grate products are designed to sit inside the opening of the window well. You need the projection out from the house in the center of the well, and the length across the back of the window well (along the foundation).

Step 2:

Using the chart below, select the window well shape and interior size range that matches your window well. The model shown will be the grate to use as your window well cover.

Please note: If your concrete well is rectangular see the Rectangular Grates page. If your well is metal with rounded front corners with the concrete poured around it, then see the standard grate page here. 

All dimensions listed are INSIDE measurements.
