When the legs are assembled in a T-shape, the fence is freestanding and doesn't require fixing to a wall. Assembling the legs in an L-shape allows it to lean against a surface. The pet fence is approximately 70cm high and can be extended from about 107cm to about 198cm in width. It can be installed in various locations such as doorways, kitchens, and stairways. The depth of the legs is approximately 39cm when assembled in a T-shape and approximately 24cm when assembled in an L-shape. The weight is approximately 6.5kg. It can also be used as a baby gate. As shown in the photos, there are scratches on the underside of the legs. This is a personal item, so there may be some minor dirt and scratches. The legs will be disassembled for shipping. Assembly should be straightforward by referring to the photos. The screws are hex screws, and a wrench is included. Materials: Steel, Wood
