The HJ-7 is a black metal joint set that allows you to create an intersection of two pipes, one above another. This joint set is mainly used to reinforce structures by building shelving supports, to strengthen the casters support, or to create a pipe grid, similar to a welded wire mesh.
Well used, this joint set can double the strength of the perpendicular tubes of your structure. This assembly can also create a grid of tubes, but unlike the HJ-4, it won't compromise your structure rigidity because no tubes required to be cut. The same result can be obtained for parallel tubes when using the HJ-13 joint set.
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-7NP

2-Take two connectors H-7 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-7 attached firmly to the two pipes . A force of 9.8 Nm is recommended for this step.
