3-Way Cube Corner Connector for 20 Series Aluminium Profiles, 20 × 20 × 20 mm

Three-way cube connector designed to join the ends of three 20 series aluminium profiles at a spatial corner. Each profile is positioned perpendicular to the other two, allowing the construction of frame, enclosure and three-dimensional structure vertices.

Access openings in the body allow the internal fasteners to be inserted and tightened. Once assembly is complete, the three included caps cover the external openings.

Features

• Type: 3-way cube corner connector.
• Material: aluminium alloy.
• Approximate dimensions: 20 × 20 × 20 mm.
• External access openings: approximately 13 mm.
• Internal fastening passages: approximately 6.5 mm.
• Joins three profiles along three perpendicular axes.
• Includes 3 caps for the external openings.
• Contents: 1 connector with 3 caps.

Compatibility

Compatible with HTA3D 20 series profiles such as the 2020 aluminium profile. It can also be used with other HTA3D profiles from the same family when their section and the assembly arrangement are suitable.

For profiles from other manufacturers, check the dimensions, central end bore and tapping system. Profiles sold under the same 2020 designation may have different internal cavities.

Installation

The three profiles are positioned against three perpendicular faces of the connector. Fasteners are inserted through the external openings and tightened into the profile ends.

The central bore of each profile may require tapping before installation. Check the required thread and screw length before tightening. Fit the caps only after the joint has been assembled and inspected.

Typical applications

• Cube-frame vertices for 3D printers.
• Enclosures and boxes made from 20 series profiles.
• Automation and robotics structures.
• Three-dimensional frames and modular furniture.

When only two profiles need to be joined at 90°, use the 2-way corner connector for 20 series profiles.

The joint capacity depends on the profiles, fasteners, profile-end tapping and load distribution.
