My roof build combined profiles, plates and corners to support several devices. Three-way connectors in my purchased hardware address a different frame shape from the two-member roof joints shown in the diary.

The item in my kit
I bought SeekLiny 2020 Three-Way Corner Connectors as part of my camper van equipment.

Where it fits my build
For the light bar, I cut an added extrusion beam and made three short drilled connectors. The rack side used quarter-twenty hardware, while the smaller 2020 extrusion used M5 hardware.
The different nuts changed the assembly sequence. A rack nut had to slide in through an opening, which meant undoing bolts I had already tightened; the smaller nuts could move and spin while I tried to start a bolt. I used an Allen key to reposition them.

My build notes
The cutting and drilling made the components, but positioning the small hardware took its own time. I recorded the difference between inserting the rack nuts and fishing the smaller nuts into place because it affected how the joint went together.
The profile, connector shape, bolt and slot nut all contributed to the assembly sequence.
Alternative products
Two alternatives to compare
An inside-corner connector joins two members from within the corner. A flat L-plate fastens across their faces, so these alternatives change both the number of directions and the position of the joint hardware.
Qjaiune 2020 Inside-Corner Connectors
These compact connectors sit within the meeting corner of extrusion profiles. Their screws fasten the connector at its two adjoining faces.
