A node for interconnecting frame members of a frame, the node including a single piece node body. A plurality of cup-shaped node connectors are disposed on the node body. Each of the plurality of node connectors include a closed end attached to the node body and an open end opposite the closed end and extending away from the node body. A sidewall extends between and connects the closed end to the open end. A tenon is formed on the open end. The tenon is shaped and sized to fit within a frame member. A transition is formed between the sidewall and the tenon defining a peripheral, radially outwardly facing groove in cooperation with the frame member, the groove shaped and sized to receive a weld.
