What Makes This Flat Corner Protector Different

Reinforcement, Not Just Protection

Most corner hardware focuses on impact resistance - but cases also need structural integrity. The 7201-35-1 is a flat corner protector designed specifically for reinforcement. Its flat, square design tightly connects the eight faces of a case, keeping the structure rigid and preventing joints from loosening over time. Think of it as the "skeleton" that holds the case together, rather than the "armor" that absorbs hits.

This is especially important for cases that are assembled, disassembled, or transported frequently - the corners take the most stress during handling, and flat corners keep everything aligned.

35mm Face Length - The Right Size for Most Cases

At 35mm face length, this corner is sized for standard case construction. It provides enough surface area to distribute stress across the joint without adding unnecessary bulk. Whether you're building flight cases, tool boxes, or wooden export crates, this size fits the majority of standard applications.

3-Hole Fixation - Simple and Secure

Three mounting holes (Ø4mm) deliver secure fixation with minimal installation effort. The triangular hole pattern provides stable anchoring with just three fasteners - no over-engineering, just reliable connection. Compatible with rivets, self-tapping screws, or spot welding.

Flat Corner vs. Spherical Corner: Which One Do You Need?

When to Choose This Flat Corner

You need case reinforcement, not impact protection. If your case needs structural integrity - keeping the joints tight and the box square - flat corners are the right choice. They don't absorb impacts; they hold the case together.

You're building a standard-size case. At 35mm face length, this corner fits most standard case applications. Not too big, not too small - just right for wooden boxes, tool cases, and aluminum frames.

You want a clean, flush appearance. Flat corners sit flush with the case surface, giving a professional, finished look. No protruding hardware, just clean lines.

You need a cost-effective reinforcement solution. At 21g with chrome plating, this corner provides reliable reinforcement without adding significant weight or cost.
