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

- Ensure you have the following parts:
- Take the two H-4NP connectors and group them around the first pipe.
- Fix the connectors by placing an M6-25BWZ with an M6-NWZ in the corresponding opening and loosely tighten. Repeat with the remaining M6-25BWZ and M6-NWZ. Make sure to place the bolts on the most accessible side.
- Insert the second and the third pipes within the openings of the HJ-4NP, and between the first and the second positioning guidelines.
- Tighten the M6-25BWZ and the M6-NWZ until the HJ-4NP is firmly attached to the three pipes.
