The HJ-23 is a black metal joint set generally used to reinforce the structure's capacity. This joint set is very similar to the HJ-13, with the only difference that it includes a hinge bracket that allows it to rotate over an opening radius of almost 360 degrees, depending on your structure configuration.

To assemble an HJ-23 you need to put two H-23 together with an AP-HINGE hinge bracket, an M6-25B bolt and an M6-N nut.

Assembly tip:
This joint set is frequently used for the assembly of folding tables, doors or on any other structures requiring a moving part. Due to the hinge bracket, we recommend using an AO-SHIM plastic shim to prevent the connector from sliding on the pipe. Consider the HJ-12 if you need similar applications of the HJ-23, but with two perpendicular tubes.

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-23NP

  1. Ensure you have the following parts:
    • 2x H-23
    • AP-HINGE bracket
    • 1x M6-25B bolt
    • 1x M6-N nut
    • 2x 28mm pipes of your choice
    • 1x T-HANDLE 5mm hex key
  2. Press the AP-HINGE bracket on the first pipe until it clips on, place opening of the bracket inside of the pipe.
  3. Group the two H-23 connectors around the first and the second pipe. Make sure that the AP-HINGE bracket teeth fit into the corresponding openings. Slide the H-23 connectors into place to lock them together.
  4. Fix the connectors together by placing the M6-25B bolt with the M6-N nut in the corresponding openings, and tighten completely until the HJ-23 joint set is firmly attached to the two pipes. Make sure to place the bolts on the most accessible side. A force between 12-14 Nm is recommended for this step.
  5. If the HJ-23 feels too tight to rotate, apply a lubricant spary to ease the mobility of the AP-HINGE bracket and to avoid damaging the plastic teeth.
