Durable silver anodised semicircular fixing plate for 2020 series aluminium extrusions. Provides high-strength structural joints for 3D printers and CNC frames.
Tired of bulky corner brackets ruining the sleek lines of your 2020 extrusion build? Whether you are building a custom CoreXY 3D printer, a camera rig, or a compact desktop enclosure, the Silver Semicircular Fixing Plate offers a low-profile, high-strength solution. This 2020B-compatible plate provides a clean aesthetic while ensuring your frame remains rigid under stress.
Probots™ Lab Verified Quality Unlike generic stamped plates that can arrive warped or with off-center holes, these plates are Probots™ Lab Verified. Our Bangalore team inspects every batch to ensure the 14mm width is consistent and the mounting holes align perfectly with standard 2020 series slots, preventing the frustration of "forced" assembly.
Material: High-Grade Aluminum Alloy
Finish: Silver Anodized (Corrosion Resistant)
Compatibility: 2020 Series (20mm x 20mm) Aluminum Extrusions
Plate Type: Semicircular / D-Shape Fixing Plate
Width: 14mm
Series Type: 2020B (Standard Slot compatible)
Mounting Hole Diameter: Designed for M5 Screws
3D Printer Frames: Perfect for reinforcing corners on Voron, Creality, or custom DIY builds.
CNC Enclosures: Provides structural bracing for acrylic or polycarbonate panels.
Camera Rigs & Sliders: Offers a professional, low-profile joint for portable photography equipment.
Modular Lab Racks: Ideal for building sturdy equipment shelving without the bulk of L-brackets.
Unlock New Capabilities (Project Evolution)
Past Projects: If you have used standard 90-degree internal corner cubes or L-brackets, you’ve likely dealt with "profile creep" where the brackets interfere with moving parts.
Feature Upgrade: This semicircular plate moves the fastening to the external face, unlocking more internal space for belts, leadscrews, or electronics.
Effort Level: Beginner. Requires only standard M5 screws and T-Nuts.
Virtual Technician & Wiring
Fastener Note: We recommend using M5x8mm or M5x10mm Button Head Screws with matching M5 T-Nuts.
Alignment Tip: Tighten screws in a cross-pattern to ensure the plate seats perfectly flush against the profile face.
Included: 1 x Semicircular Fixing Plate (Silver) for 2020B Profile
Is this plate compatible with 2040 profiles? Yes, it can be used on the 20mm side of a 2040 extrusion.
What screw size should I use? The holes are optimized for M5 hardware.
Is the silver finish painted or anodized? It is professionally anodized for superior scratch and corrosion resistance.
Does it include the T-nuts? No, this is the plate only. T-nuts and screws are sold separately.
Will this fit 'V-Slot' profiles? Yes, it is compatible with both T-Slot and V-Slot 2020 profiles.
Can I use this for heavy-duty load-bearing? It is designed for structural framing; for heavy loads, use in pairs on both sides of the profile.
What is the thickness of the plate? The plate is approximately 4mm thick for high rigidity.
Is it made of steel or aluminum? It is made of high-grade aluminum to keep the weight low and strength high.
How many mounting holes does it have? This semicircular plate features 3 precision-drilled mounting holes.
Does the 14mm width cover the entire 20mm face? No, it is intentionally 14mm to sit centered within the face or allow for specific clearances.
Is it compatible with 2020B slot variants? Yes, the hole spacing is designed for the 2020B series standard.
Can I paint this plate? While it is anodized, you can prime and paint it if a custom color is needed.
Do the edges come deburred? Yes, all edges are smooth to prevent snagging or injury during assembly.
Is this suitable for outdoor use? Yes, the aluminum construction and anodized finish are highly weather-resistant.
Does it come with a protective film? Standard batches are bulk-protected, but we ensure they are scratch-free.
Can I use M4 screws instead? You can, but the head size may be too small for the hole diameter without a washer.
What is the total length of the plate? The plate measures approximately 40mm-45mm at its longest point.
Is this plate compatible with 2525 profiles? No, this is specifically for 20mm (2020) series profiles.
How do I clean the plate? Simply wipe with a microfiber cloth; avoid harsh acidic cleaners.
Is this a cast or CNC-machined part? These are typically precision-stamped and then CNC-finished for edge accuracy.
