These Redwood Windowboxes can be used as planters or set on a ledge as a stand-alone planter. They are a natural choice for an attractive container built to suit and made to last. The Pasadena Planter is hand-assembled by an experienced, third-generation craftsman. Responsibly harvested and constructed of high-quality California Redwood, the lumber is architecturally graded at "Clear". The wood is also kiln-dried to ensure it can take any abuse that Mother Nature can dish out. Brackets for this box are NOT included but our Window Box Bracket - 10" Shelf (pair) works perfectly. Width and height are fixed respectively, at 9.75"W x 8"H (outside dimensions).
