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.

To assemble an HJ-7 you need to combine two H-7 together with one M6-25B bolt and one M6-N nut.

Assembly tip:
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.

Installation Steps:
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

  1. Ensure you have the following parts:
    • 2x H-7
    • 1x M6-25B bolt
    • 1x M6-N nut
    • 2x 28mm pipes of your choice
    • 1x T-HANDLE 5mm hex key
  2. Take the two H-7 connectors and group them around the first pipe.
  3. Fix the connectors by placing the M6-25B bolt with the M6-N nut in the corresponding openings and loosely tighten. Make sure to place the bolts on the most accessible side.
  4. Slide the second pipe into the remaining opening of the HJ-7 joint set.
  5. Position at the desired place and tighten completely until the HJ-7 is firmly attached to the two pipes. A force between 12-14 Nm is recommended for this step.
