The HJ-3NP is a chrome-plated joint set with antistatic properties (ESD) that allows creating a four-pipe intersection or a corner. This joint set is excellent for making corner pegs at 90 degrees. It is also often used in the center of structures to create strong counterweight and in the bottom of structures to fix stem-mount casters.
To assemble an HJ-3NP you need to combine two H-2NP and an H-4NP together with three M6-25BWZ bolts and three M6-NWZ nuts. This connector is a little bit trickier to assemble than the HJ-1NP or HJ-2NP, but when fixing both H-2NP parts together first, you should have an installed HJ-3NP connector in no time.
This joint set is designed with 14 striations for a better grip on the plastic coating of the 28 mm pipes. It also includes 3 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-3

2- Take two connectors H-2NP and a connector H-4NP and group them around the P1 pipe.
3-Take three M6-25BWZ bolts and three 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-2NP 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-2NP attached firmly to the four pipes . A force of 9.8 Nm is recommended for this step.
