Cast – 90 Degree Corner Bracket Black

$2.21 Inc. GST

This cast aluminium component establishes perpendicular right-angle joints between modular aluminium profiles. Featuring integrated structural alignment tabs, the bracket locks into profile tracking channels to prevent rotation under torsional loads. Typical applications include constructing frame corners, mechanical braces, and rigid reinforcements for 3D printer enclosures, CNC machine bases, linear motion gantries, and automated frameworks. Dimensioned at 20mm x 20mm x 17mm, the component is compatible with V-Slot linear rails and standard 20 Series T-Slot profiles featuring 4mm slot widths.

Description

Technical Overview

The Cast – 90 Degree Corner Bracket serves as a standard, high-strength structural connection component engineered specifically to establish rigid perpendicular joints within modular aluminium framing layouts. This cast bracket allows for straightforward, right-angle interfacing between structural profiles with minimal assembly complexity.

Furthermore, the design features integrated structural alignment tabs designed to lock directly into the extrusion tracking channel. These anti-rotation standoff teeth ensure an accurate, square connection between intersecting profiles while preventing the assembly from twisting under heavy torsional loads.

Applications

Engineers and builders primarily use this 90-degree cast corner bracket to construct structural frame corners, mechanical braces, or rigid structural reinforcements across various modular frame layouts. Consequently, it delivers an optimal, heavy-duty mechanical connection point for stabilizing linear motion gantries, custom 3D printer enclosures, CNC machine bases, and general automated framework lines.

In addition, the physical profile of the bracket seamlessly fits 20mm x 20mm x 17mm footprints, making it universally compatible with V-Slot linear rail and standard 20 Series T-Slot structural profiles featuring a 4mm wide tracking channel slot. By utilizing variable fastener paths across the flush and alignment-toothed faces, users can execute highly reliable perpendicular joints directly on the machine frame.

Maker Store Tips and Tricks

  • Note that since the cast corner brackets feature standoff alignment teeth in one direction, you must use a 10mm Low Profile Screw along that directional plane to ensure sufficient thread depth.

  • For the opposing flush mount orientation face, use an 8mm low profile screw along with standard M5 Tee Nuts to secure a perfectly flush seat arrangement.

  • Hand-tighten both sides lightly into the extrusion tracking paths before executing final torque steps to maximize cross-frame perpendicularity.
