The HJ-4NP is a chrome-plated joint set with antistatic properties (ESD) that allows creating 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-7NP connectors. This HJ-4NP 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.
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.
See the installation steps tab to view how to assemble this connector.
Non-Electric Conductivity Version:
A version of this joint set is offered without antistatic properties: HJ-4

2- Take two connectors H-4NP and group them around the P1 pipe.
3-Take two M6-25BWZ bolts and two M6-NWZ nuts and insert them into the corresponding openings. Make sure to put the bolts on the more accessible side.
4- Tighten the M6-25BWZ bolts and nuts M6-NWZ together a few threads , but no more.
5- Insert the P2 and P3 pipes within the HJ-4NP between the first and second guides as shown in the plan .
6- Tighten completely the M6-25BWZ bolts and M6-NWZ nuts together until the HJ-4NP attached firmly to the three pipes . A force of 9.8 Nm is recommended for this step.
