Black 5-Hole L-Shaped Connecting Plate for 2020 Aluminum Profile

Specifications

• Material: 6063-T5 Aluminum Alloy

• Thickness: 4mm (Heavy Duty)

• Finish: Industrial Black Anodized

• Configuration: 5-Hole L-Shape (90 Degree)

• Hole Spacing: 20mm (Standard 2020 Spacing)

• Hole Diameter: 5.5mm (Optimized for M5 Fasteners)

• Overall Dimensions: 60mm x 60mm

• Weight: 45g

Key Applications & Projects

• High-Speed 3D Printers: Ideal for the outer frame joints of Voron, RatRig, and custom CoreXY builds.

• Desktop CNC Routers: Provides the necessary bracing for base frames and gantry supports.

• Sim-Racing Rigs: Use to reinforce steering wheel mounts and pedal plates where high-torque rigidity is required.

• Industrial Workstations: Perfect for building modular lab benches or high-strength equipment racks.

Unlock New Capabilities (Project Evolution)

• Past Projects: If you have relied on internal 90° hidden brackets, you’ve likely noticed they can "pivot" slightly if the profile ends aren't cut perfectly square.

• Feature Upgrade: This external plate bridges the gap between two profiles, physically locking them in place from the outside. It unlocks the ability to build much taller and wider frames without sacrificing squareness.

• Effort Level: Beginner. Requires 5 x M5 screws and T-Nuts. No drilling or tapping required.

Virtual Technician & Tips

• Probots™ Logic-Safe ????️ Alignment: For maximum rigidity, we recommend using this plate in conjunction with internal corner brackets. Use M5x10mm Button Head screws for a flush, professional "stealth" look that matches the black anodized finish.

• Installation Tip: Tighten the centre screw first to set the initial alignment, then use a machinist's square to verify the 90° angle before locking down the remaining 4 screws.

Included Accessories

• 1 x Black 5-Hole L-Shaped Connecting Plate (2020 Series)

Frequently Asked Questions (FAQ)

1. Does this plate fit V-Slot or T-Slot? It is compatible with all standard 2020 series profiles, including V-Slot and T-Slot.

2. Is it made of steel or aluminum? It is made of high-strength 6063-T5 aluminum, offering better weight-to-strength ratio and corrosion resistance than steel.

3. What length of screw should I use? We recommend M5x10mm Button Head screws for 2020 profiles.

4. Can I use this for 2040 profiles? Yes, it fits on the 20mm face of a 2040 profile.

5. Does it come with screws and nuts? No, this is the plate only. Fasteners are sold separately.

6. How many do I need for a 3D printer? Most builders use 4 for the base and 4 for the top corners for maximum stability.

7. Is the black finish scratch-resistant? The industrial anodization is very durable, but it can be scratched by hard metal tools; use plastic-tipped wrenches if concerned.

8. Will this fit a 3030 profile? No, this is specifically for the 20mm (2020) series. 3030 profiles require different hole spacing.

9. What is the thickness of the plate? It is a robust 4mm thick, preventing any flexing under load.

10. Do I need to drill the aluminum profile to use this? No, it mounts directly into the profile slots using T-nuts.

11. Is this stronger than a 3-hole L-plate? Yes, the 5-hole design provides two additional anchor points for significantly higher torque resistance.

12. Can I use this for outdoor projects? Yes, anodized aluminum is highly resistant to weather and corrosion.

13. Is it compatible with 80/20 profiles? Yes, as long as they are the metric 20mm series.

14. What is the hole diameter? The holes are 5.5mm, perfect for M5 screws.

15. Does it matter which side faces the profile? Both sides are precision-finished, but typically the "smoother" anodized side faces outward.

16. Can I mount two of these on one corner? Yes, mounting one on the front and one on the back of a joint creates an "unbreakable" connection.

17. What happens if my profile cut isn't 90 degrees? This plate will help force the profiles into a 90-degree alignment, correcting minor cutting errors.

18. Is this plate cast or milled? It is precision-milled and stamped for exact hole alignment.

19. Will this plate rust? No, aluminum does not rust like iron or steel.

20. Can I use this to mount a motor? While not a dedicated motor mount, the holes can sometimes be aligned with NEMA 17 mounting patterns for custom brackets.
