This is a flat snap-fit connector for 2040 V-slot aluminum extrusion profiles, designed to join two profiles side by side (or four 2020 profiles in a 2×2 layout) in a single plane.

It connects the extrusions securely without screws or metal plates, making it ideal for flat frame extensions, base reinforcements, or modular constructions.

The design fits directly into the V-slot channels with a tight friction-fit, providing alignment and support while keeping the surface clean and low-profile.
