The HJ-12 is a black metal joint set that rotates 360 degrees. Very similar to the HJ-1, the HJ-12 allows a rotation once this connector is fixed.
This joint set is frequently used to create doors, movable separators and foldable shelves. Psst! If you don't need this joint set to be mobile, the HJ-1 may be a better fit for your needs.
This joint set is designed with 4 striations for a better grip on the plastic coating of the 28 mm pipes. It also includes 2 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.
Antistatic Version (ESD):
An electric conductivity version if offered if you wish to build antistatic structures: HJ-12NP

- Ensure you have the following parts:
- 2x H-12
- 1x AP-HINGE bracket
- 1x M6-25B bolt
- 1x M6-N nut
- 2x 28mm pipes of your choice
- 1x T-HANDLE 5mm hex key
- Take the AP-HINGE bracket and press it on the first pipe until it clips on, place the opening of the AP-HINGE toward inside of your structure.
- Group the two H-12 connectors around the first pipe so that the teeth of the AP-HINGE fit into the corresponding openings of the connectors, ensuring proper installation.
- Fix the connectors together by placing the M6-25B bolt with the M6-N nut in the corresponding openings and completely tighten until the HJ-12 joint set is firmly attached to the pipe. Make sure to place the bolts on the most accessible side. A force between 12-14 Nm is recommended for this step.
- If the HJ-12 joint set feels too tight to rotate, apply a lubricant spray to ease the mobility of the AP-HINGE and to avoid damaging the plastic teeth.
- Add a metal screw to the pre-drilled reinforcement hole to secure the connector on the second pipe. This can be useful when this connector is used to make shelvings and prevent the material from falling.
Use without the AP-HINGE when space is limited and you need to overlap two joints.
