Abstract: Outdoor structures and clips for attaching objects to frame members of outdoor structures are provided. A frame member includes a channel having an opening defined between two flanges having a flange thickness. A clip for attaching an object to the frame member includes a head sized to be received in the channel of the frame member via the opening and frictionally engaged with the channel upon rotation of the head when the head is received in the channel. The clip includes a body attached to the head and configured to engage with the object. The head and the body of the clip define a gap therebetween for receiving the flanges when the head is engaged with the channel. The gap has a gap thickness that is smaller than the flange thickness to define an interference fit between the flanges and the clip.
