These devices were conceived for building a fence from corrugated board alone. With the perimeter marking and the installation of poles, one person can handle it, and for securing sheets and jumpers, second hands are needed that can replace cunning brackets.
"Second hands" are made of a rectangular profile pipe and corner, you will also need bolts and thumbs for fixing. Devices are brackets with customization, one type is designed for jumpers, the second for mounting sheets on a finished frame.
After the columns are installed on two of them, devices are placed on which the jumper is installed, the level is adjusted with the help of clamping bolts, then welding works follow.
The second type of bracket already works with jumpers on which they are installed and they regulate the level and height of the profile sheet.
