摘要 An adjustable window well grate is disclosed. The grate includes a plurality of individually adjustable elongate members, each of which has first and second elongated slidable sections, preferably U-shaped stringer sections which are slidable relative to each other to enable one to easily adjust the overall length of the elongate member.

In addition to the elongate members, the adjustable grate includes a plurality of cross supports for supporting and connecting a plurality of the elongate members together.
