What Makes This Flat Corner Protector Different

Chrome Plated Mild Steel - Cost-Effective Corrosion Protection

The 7201-40-2-FE-CR is constructed from mild steel with a chrome plated finish. 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 compared to stainless steel alternatives. The chrome plating also provides a smooth, glossy appearance that enhances the professional look of any case.

Raised Dot Surface Detail - Distinctive Design

This model features a single raised dot on one face - a subtle design detail that distinguishes it from the 7201-40-1 (which has a dimple on one face). The other two faces remain smooth. Both models share identical dimensions, thickness, weight, and hole configuration. The choice between the two comes down to the surface detail that best complements your case design.

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.

When to Choose This Chrome Plated Flat Corner

You need case reinforcement at a cost-effective price. Chrome plated mild steel offers excellent corrosion protection at a lower cost than stainless steel. Choose this for standard applications where budget is a consideration.

You prefer a raised dot detail. The single raised dot on one face adds a tactile element while keeping the overall profile flat. If you prefer a recessed detail, consider the 7201-40-1.

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 a bright, professional appearance. The chrome plating provides a glossy, mirror-like finish that looks professional on any case.

What's the difference between 7201-40-1 and 7201-40-2?

Both have the same 40mm face length, 0.9mm thickness, 3-hole Ø4mm design. The only difference is the surface detail on one face: 7201-40-1 has a dimple (concave), while 7201-40-2 has a raised dot (convex). The other two faces are smooth on both models.

What's the difference between chrome plated mild steel and stainless steel?

Chrome plated mild steel offers cost-effective corrosion protection with a bright, glossy finish. Stainless steel provides inherent corrosion resistance throughout the material - it won't scratch off or wear away. Choose chrome plated for standard applications where budget is a consideration; choose stainless steel for medical, marine, or food industry applications.

What type of case is this corner suitable for?

The 7201-40-2 is suitable for flight cases, tool boxes, military cases, wooden export boxes, instrument cases, and most standard case sizes requiring corner reinforcement.

How do I install this corner protector?

Position the corner against the case edge, mark the hole positions using the 3 holes as a guide, pre-drill with a 3.5mm bit, then secure with rivets, self-tapping screws, or spot welding.

Can you make these in stainless steel or different finishes?

Yes. Custom orders available for stainless steel, black chrome, powder coating, and other finishes. Contact us with your requirements.
