  • Compatible with 28 mm pipes
  • Assembly required

The HJ-7A is a black metal joint set that allows you creating an intersection of two pipes, one above another. Very similar to the HJ-7, the only difference is that it is not completely closed. This connector allows the top tube to be in contact with a surface.

To assemble an HJ-7 you need to combine two H-7A together with one M6-25B bolt and one M6-N nut.

Assembly tip:
Very useful when building a tight area with the AI-CORNER and AI-CENTER accessories and you want to create a wire mesh under the surface. This connector also avoids the use of AO-SHIM. For more strengthen structures, we recommend using the HJ-7 as much as possible.

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-7ANP

  1. Ensure you have the following parts:
  2. Take the two H-7A connectors and group them around the first pipe.
  3. Fix the connectors by placing the M6-25B with the M6-N in the corresponding openings and loosely tighten.
  4. Slide the second pipe into the remaining opening of the HJ-7A joint set.
  5. Position at the desired place and tighten completely until the HJ-7A is firmly attached to the two pipes.
