Round angle joint set
In stock
- Compatible with 28 mm pipes
- Assembly required
- Used to create handle
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.
To assemble an HJ-90 you need to put two H-90 together with two M6-25B bolts and two M6-N nuts.
Technical Information:
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.
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-90NP
