Black 90° Corner Connector Bracket for 2020 V-Slot Aluminum Profile

Specifications

• Material: Die-Cast Aluminum Alloy (ADC12)

• Finish: Industrial Black Anodized (Corrosion Resistant)

• Compatibility: 2020 Series (20mm x 20mm) V-Slot & T-Slot Profiles

• Angle: 90 Degree (Right Angle)

• Dimensions: 20mm x 20mm x 17mm

• Mounting Hole Size: 9mm x 6mm (Standard Oval Slot)

• Fastener Compatibility: Optimized for M5 Low-Profile or Button Head Screws

Key Applications & Projects

• High-End 3D Printers: Essential for Voron, RatRig, or Creality frame reinforcements.

• Desktop CNC Routers: Provides the necessary bracing for precision axis movement.

• Camera Sliders & Rigs: Sleek black finish is perfect for professional photography gear.

• Modular Workstations: Build custom electronics benches with a clean, "stealth" aesthetic.

Unlock New Capabilities (Project Evolution)

• Past Projects: If you have previously relied on basic 3-way corner cubes or internal hidden L-joints, you know they can be difficult to tighten once the frame is fully assembled.

• Feature Upgrade: These external corner brackets allow for post-assembly reinforcement and "squaring up" without dismantling the entire rail system.

• Effort Level: Beginner. Simply slide in T-Nuts and bolt directly to the profile face.

Virtual Technician & Wiring

• Probots™ Logic-Safe Alignment: To ensure a perfect 90° joint, we recommend using a machinist's square during assembly. Tighten the M5 screws incrementally to prevent the bracket from "walking" as the T-Nut seats in the slot.

• Fastener Tip: Use M5x8mm or M5x10mm screws. For the cleanest look, use Black Oxide Button Head screws to match the bracket finish.

Included Accessories

• 1 x 90° Corner Connector Bracket (Black Anodized)

• (Note: T-Nuts and Screws are sold separately)

Frequently Asked Questions (FAQ)

1. Does this fit standard T-Slot profiles from local suppliers? Yes, it is compatible with both European standard 2020 T-Slot and V-Slot profiles.

2. Is the black finish paint or anodized? It is professionally anodized, which is more durable and scratch-resistant than paint.

3. What is the benefit of the oval mounting hole? It allows for slight adjustment during assembly to ensure your frame is perfectly square.

4. Can I use M6 screws with this? No, the hole is designed for M4 or M5 screws, with M5 being the recommended standard.

5. How many do I need for a 3D printer cube frame? For a standard 4-post cube, you typically need at least 8 brackets (2 per vertical pillar).

6. Will the black finish peel off over time? No, anodization is an electrochemical process that becomes part of the metal surface.

7. Is this bracket compatible with 2040 profiles? Yes, it fits perfectly on any 20mm face of a 2040 or 2060 profile.

8. Do I need to drill holes in my aluminum profile? No, these brackets use the existing slots and T-Nuts for a "no-drill" assembly.

9. Is this stronger than the hidden L-shape internal connectors? Yes, external corner brackets generally provide higher structural rigidity against twisting forces.

10. What is the weight of one bracket? Each bracket weighs approximately 15 grams.

11. Can these be used for outdoor structures? Yes, the aluminum alloy and anodized finish are highly resistant to rust.

12. What screw length do I need? M5x8mm is the standard; use M5x10mm if you are adding a washer.

13. Are these brackets sold in packs? These are sold individually so you can buy the exact amount your project requires.

14. Is there a "right side up" for these? No, they are symmetrical and can be used in any 90-degree orientation.

15. Can I use these to mount panels? While primarily for joints, they can be used as a support ledge for acrylic or wood panels.

16. Are the edges sharp? No, these are die-cast with rounded edges for safe handling.

17. What happens if I over-tighten the screw? The bracket is cast aluminum; over-tightening might strip the T-nut or dent the profile before breaking the bracket.

18. Can I use these with 1-inch (80/20) profiles? No, these are specifically for the 20mm metric series.

19. Do they come with a warranty? They are covered under the standard Probots quality guarantee against manufacturing defects.

20. Is the color a matte or glossy black? It is a professional semi-matte industrial finish.a
