The HJ-3 is a black metal joint set that allows you to create 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-3 you need to combine two H-2 and an H-4 together with three M6-25B bolts and three M6-N nuts. This connector is a little bit trickier to assemble than the HJ-1 or HJ-2, but when fixing both H-2 parts together first, you should have an installed HJ-3 connector in no time.

Technical Information:
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.

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-3NP

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