The HJ-4 is a black metal joint set that allows you to create a three-pipe intersection on two axes. This joint set is the best option when you need to create separations without weakening the rigidity of your structure. It will give you the option of making a pipe grid, similar to welded wire mesh, but with fewer tubes than it would require with HJ-7 connectors. This HJ-4 will also be ideal when you need to create an intersection between two perpendicular pipes, but you don't want to weaken the strength of a long pipe or long pipe series. It allows you to secure stem-mount casters easily at the bottom of your structure.

To assemble an HJ-4 you need to combine two H-4 together with two M6-25B bolts and two M6-N nuts.

Technical Information:
This joint set is designed with 12 striations for a better grip on the plastic coating of the 28 mm pipes. It also includes 6 additional pre-drilled reinforcement holes to ensure extra strength to your structure. By adding a self-drilling screw F-A85/8, you will solidify the connector joints positioned on a corner where there is a higher risk of impact.

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-4NP

1- Make sure you have the following parts:
2 H-4
2 M6-25B
2 M6-N
3 28mm pipes of your choice
1 Allen key or one drill equipped with an Allen Key 5mm tip
2- Take two connectors H-4 and group them around the P1 pipe.
3-Take two M6-25B bolts and two M6-N nuts and insert them into the corresponding openings. Make sure to put the bolts on the more accessible side.
4- Tighten the M6-25B bolts and nuts M6-N together a few threads , but no more." 5- Insert the P2 and P3 pipes within the HJ-4 between the first and second guides as shown in the plan .
6- Tighten completely the M6-25B bolts and M6-N nuts together until the HJ-4 attached firmly to the three pipes . A force of 9.8 Nm is recommended for this step.
