2020 Aluminum Extrusion: My Roof-Mount Build Notes
My light-bar mount joined an added 2020 extrusion beam to the existing roof rack. The rail, connectors and two different fastener arrangements all affected the order of assembly.
The light bar needed a position above the existing rack, so I added a beam and three drilled connections. The slot let me position attachments along the extrusion, but it also made the nut-insertion sequence part of the job.
The smaller nuts could move or spin while I tried to start a bolt. The rack nuts entered through a wider opening, which meant loosening already-tightened bolts when I needed to add another nut. Those are the practical details behind my interest in extrusion hardware.

Joining the Smaller Beam to the Existing Rack Profile
I cut the added 2020 beam to 58 inches with the miter saw.
I joined it to the rack with three drilled mounts, using different hardware on the two profiles.
I used an Allen key to reposition the small nuts as they moved and spun while I started the bolts.

My Takeaway for Choosing the Kit
I would choose the rail and joint hardware together. IXGNIJ supplies two-meter T-slot stock, ZYLtech offers one-meter T-slot lengths, and the SeekLiny comparison changes to a one-meter V-slot profile. The listed rail length does not by itself settle the nut, connector or slot-geometry choice.

Black aluminum profile
My roof-mount work involved cutting the rail stock, joining short pieces and fitting brackets around the devices. A useful cut list identifies each member and the joint at both ends before the stock is divided. Keep the actual profile reference with the selected nuts and plates, including the locations where a driver must reach the screws. That connects the long stock purchase with the separate fitting work documented in the roof-camera and light projects.

Two Alternatives to Compare
The ZYLtech stock uses a 2020 T-slot profile, while the SeekLiny stock uses a 2020 V-slot profile. Both are supplied in one-meter lengths, shorter than the two-meter stock in my materials. Length and slot geometry are the main differences for planning cuts and selecting the associated hardware.
