# Gussets

Gussets are flat structural plates used to reinforce joints between two or more components, typically at corners or intersections of extrusion in FRC robots.

</div>## Purpose

Gussets:

- Strengthen 90° and angled joints
- Reduce flex in structural frames
- Distribute load across multiple fasteners
- Improve rigidity without adding much weight

</div>## Custom Gussets

Custom gussets are designed by teams and usually cut from sheet material.

**Common materials:**

- 5052 aluminum (most common)
- Polycarbonate (for light-duty or flexible use)
- SRPP (for lightweight structural applications)

**Characteristics:**

- Fully customizable geometry
- Can be optimized for weight and packaging
- Require CAD, machining, or sponsor manufacturing (laser/waterjet/CNC)

</div>## Vendor Gussets (WCP and Similar Suppliers)

Vendor gussets are pre-designed and pre-cut parts from suppliers such as West Coast Products.

**Characteristics:**

- Standardized hole patterns (often 0.5" spacing compatible)
- Fast to integrate into designs
- Consistent strength and manufacturing quality
- Reduce design and fabrication time

**Typical features:**

- Pre-drilled patterns for 1/2" or 1x1 extrusion
- Multiple angle options (90°, 45°, L-brackets, etc.)
- Lightweight pocketed designs

</div>## When to Use Each

- Custom gussets → when optimizing weight, packaging, or unique geometry
- Vendor gussets → when speed, simplicity, and reliability are more important

</div>## Key Idea

Gussets reinforce structural joints in FRC robots. Custom gussets provide maximum design flexibility, while vendor gussets offer fast, reliable, and standardized solutions for common structural connections.
