The HJ-7A is a black metal joint set that allows you creating an intersection of two pipes, one above another. Very similar to the HJ-7, the only difference is that it is not completely closed. This connector allows the top tube to be in contact with a surface.
Very useful when building a tight area with the AI-CORNER and AI-CENTER accessories and you want to create a wire mesh under the surface. This connector also avoids the use of AO-SHIM. For more strengthen structures, we recommend using the HJ-7 as much as possible.
See the installation steps tab to view how to assemble this connector.
Antistatic Version (ESD):
An electric conductivity version if offered if you wish to build antistatic structures: HJ-7ANP

2-Take two connectors H-7A and group them around the P1 and P2 pipes.
3-Take a M6-25B bolt and a M6-N nut and insert them into the corresponding openings. Make sure to put the bolt on the more accessible side.
4- Tighten completely the M6-25B bolt and M6-N nut together until the HJ-7A attached firmly to the two pipes . A force of 9.8 Nm is recommended for this step.
