4 way cross joint set
- Compatible with 28 mm pipes
- Assembly required
- Joint set with antistatic properties (ESD)
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

- Ensure you have the following parts:
- Fix an H-2NP connector in the inner corner with an H-4NP and loosely tighten around the first pipe using an M6-25BWZ with an M6-NWZ in the corresponding openings.
- Repeat with the remaining H-2NP and fix to the connectors already in place, and loosely tighten the remaining M6-25BWZ and M6-NWZ in the corresponding openings.
- Insert the second, third, and fourth pipe within the openings of the HJ-3NP, and between the first and the second positioning guidelines.
- Tighten the M6-25BWZ and the M6-NWZ until the HJ-3NP is firmly attached to the four pipes.
