Description
Technical Overview
The Curved Joining L Plate is a structural reinforcement hardware element engineered to interconnect linear profiles at variable geometries. Manufactured from brushed aluminium and finished with a black anodised protective layer, this plate acts as a rigid junction across multiple orientation axes. It provides structural mounting surfaces specifically tailored for V-Slot modular framing setups.
The hardware component features a curved angular indexing slot structure that allows configuration adjustments at multiple precise engineering orientation increments. Specifically, the plate facilitates fixed mechanical connections at rigid 90°, 67.5°, 45°, and 22.5° angles. Beyond profile-to-profile integration, the mounting plate includes dedicated clearance provisions for securing 10mm smooth cylindrical rods parallel or perpendicular to the primary structural channels.
Applications
Engineers and builders utilize the black anodised plate to construct variable-angle trusses, supporting frameworks, and automated mechanical linkages. It serves as a primary positioning bracket in precision equipment architectures, including multi-axis robotics platforms, custom 3D printer chassis systems, laser cutter and engraver structures, and specialty coordinate plotting machines such as egg bots.
The plate allows builders to transition smoothly from rigid orthogonal framing to dynamic angular configurations without requiring complex machining or custom mitered cuts on the profile ends. Additionally, the integrated 10mm smooth rod positioning holes simplify the assembly of linear guide rails alongside structural profiles. This capability makes the bracket a highly useful hardware component for complex prototyping configurations, laboratory automation, and custom industrial manufacturing rigs.

Maker Store Tips and Tricks
-
When aligning the plate at a specific pre-set angle, loose-fit all structural low-profile screws into the extrusion channel T-nuts before applying final torque spec to prevent binding.
-
Use standard drop-in or tee nuts along with low-profile M5 screws to secure the plate flush against the V-Slot outer channels.
-
Verify orientation and perpendicular alignment using an external engineering square or angle finder tool before completing final torque steps on heavy-duty joints.
