What Makes This Flat Corner Protector Different

Smooth Surface - Clean, Minimalist Design

The 7201-40-FE-CR features a completely smooth surface across all three faces - no dimples, no raised dots, no markings. This is the base model of the 40mm flat corner series, offering a clean, minimalist appearance that suits any case design.

Chrome Plated Mild Steel - Cost-Effective Corrosion Protection

Chrome plating provides a bright, corrosion-resistant surface that protects the steel from rust and wear. This finish offers excellent durability for standard applications while remaining cost-effective. The chrome plating also provides a smooth, glossy appearance that enhances the professional look of any case.

40mm Face Length - Extended Coverage

At 40mm face length, this corner provides more surface coverage than standard 35mm models. The larger footprint distributes stress across a wider area, making it ideal for larger cases and applications requiring additional reinforcement.

3-Hole Fixation

Three mounting holes (Ø4mm) deliver secure fixation with minimal installation effort. Compatible with rivets, self-tapping screws, or spot welding.

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

When to Choose This Smooth Flat Corner

You want a clean, minimalist appearance. No dimples, no raised dots - just a smooth, professional flat corner on all three faces. This is the standard finish for case reinforcement.

You need cost-effective corrosion protection. Chrome plated mild steel offers excellent protection at a lower cost than stainless steel, making it ideal for standard applications.

You need a larger corner for bigger cases. At 40mm face length, this corner provides extended coverage for larger cases and applications requiring additional reinforcement.

You want versatility. The smooth surface works with any case design without distracting visual details.

Applications

Installation & Maintenance

Installation:

• Position the corner against the case edge

• Pre-drill with a 3.5mm bit
• Secure with rivets, self-tapping screws, or spot welding

Maintenance & Storage:

• Wipe with a soft cloth and mild detergent
