Simple, removable, rigid, and aesthetic, these different assembly parts allow for custom fabrication of aluminum frames using 50×30 tubular profiles or 80×40 and 50×40 clip-on profiles. The connections between the parts and profiles are made by tightening the locking plate. This product is the first bracket that allows for the assembly of aluminum profiles to create a gate frame. This patented product consists of an insert that slides into the upright and a half bracket positioned in the crosspiece, which work together during assembly (patent). A tightening plate will lock the two products together after tightening. The simple machining and the range of accessories that make up this range allow for precise and aesthetic work while ensuring the necessary rigidity for the gate frame.
