Black 3 Way End Angle Bracket Connectors

Product Description

The Black 3 Way End Angle Bracket Connectors are an essential piece of hardware for building perfectly square, three-dimensional corners on your custom frames. Designed specifically for Europe standard 2020 series aluminum extrusions with a 6mm slot, this internal corner joint allows you to connect three pieces of extrusion together at a single 90-degree intersection. Unlike bulky external brackets, this 3-way connector slides entirely inside the extrusion slots, creating a flush, clean, and professional exterior finish.

Manufactured from high-strength zinc alloy, these brackets provide excellent structural rigidity without interfering with exterior panels, acrylic enclosures, or linear rails that need to sit flat against the outside of your frame. This makes them highly popular for building enclosed CoreXY 3D printers, custom CNC electronics boxes, and desktop laser engraver chassis.

The premium black finish perfectly complements black-anodized aluminum profiles, maintaining a sleek and stealthy aesthetic. For quick and easy installation, the Black 3 Way End Angle Bracket Connectors come complete with the necessary set screws (grub screws). Simply slide the bracket into the extrusion ends and tighten the screws to lock the profiles firmly together, preventing any twisting or flexing during high-speed machine operation.

Key Features

• 3-Way Corner Joint: Connects three separate 2020 series aluminum extrusions at a single 90-degree corner.

• Internal Flush Mounting: Slides directly into the 6mm T-slot or V-slot, leaving the outside faces of the extrusion completely flat for mounting panels or linear rails.

• Included Set Screws: Comes with the necessary grub screws for an immediate, secure, and hassle-free installation.

• High-Strength Material: Cast from durable zinc alloy to provide robust structural stability and prevent chassis flex.

• Stealth Black Finish: Perfectly matches black-anodized profiles for a unified, premium look on your custom workshop builds.

Applications

• Creating completely flush, hidden corners on custom DIY CNC machine enclosures and bases.

• Building enclosed chassis for CoreXY 3D printers where acrylic panels must sit flat against the frame.

• Assembling rigid, professional-looking laser engraver frames and electronics boxes.

• Designing clean, modular workbenches and custom workshop shelving without bulky external brackets.
