Gateway Arbor Simple Arch with Plant Supports on the sides and a unique frame on the top of the arch. Its total height measures 100" tall, with the top sunburst at 19" tall. The opening is 81" to the ground. The inside is 45.5" wide, and the outside is 48" wide by 24" deep. Comes apart into three pieces: 1 top and two sides. Furrows are how it slips together. We recommend laying it down to fit together and then standing it up.
