  • Compatible with 28 mm pipes
  • Assembly required

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. Ensure you have the following parts:
  2. Take the two H-4 connectors and group them around the first pipe.
  3. Fix the connectors by placing an M6-25B with an M6-N in the corresponding opening and loosely tighten. Repeat with the remaining M6-25B bolt and M6-N nut.
  4. Insert the second and the third pipes within the openings of the HJ-4, and between the first and the second positioning guidelines.
  5. Tighten the M6-25B and the M6-N until the HJ-4 is firmly attached to the three pipes.
