The HJ-90 is a black metal joint set that allows you to connect two 28 mm pipes to create a 90-degree corner. This joint set is often used for ergonomic cart handles.
This joint set is designed with 8 striations for a better grip on the plastic coating of the 28 mm pipes. It also includes 4 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-90NP

- Ensure you have the following parts:
- 2x H-90
- 2x M6-25B bolts
- 2x M6-N nuts
- 2x 28mm pipes of your choice
- 1x T-HANDLE 5mm hex key
- Group the two H-90 connectors around the first and the second pipe, between the first and the second positionning guidelines.
- Fix the connectors together by placing the M6-25B bolts with the M6-N nuts in the corresponding openings. Make sure to place the bolts on the most accessible side.
- Tighten completely until the HJ-90 joint set is firmly attached to the two pipes. A force between 12-14 Nm is recommended for this step.
