Heavy Duty Corner Protector 41mm Chrome Plated Large Case Hardware

Triangle Corner Protector for Large Cases - 41mm Chrome Plated 3 Holes

What Makes This Heavy Duty Triangle Corner Protector Different

Largest Coverage in the Triangle Series - 41mm

At 41mm face length, this is the largest model in the triangle corner lineup. It provides maximum edge coverage for thick plywood panels (15-25mm) that smaller corners leave exposed. This is the triangle corner for large cases that need serious reinforcement.

Heavy Duty 1.5mm Thickness - 3x Stronger

At 1.5mm thick, this model provides 3x the metal thickness of standard 0.5mm triangle corners and nearly double the 0.7-0.8mm options. It won't bend under heavy loads - ideal for industrial storage boxes, heavy equipment cases, and large wooden containers that take serious abuse. At 41g per corner, eight corners add 328g of substantial protection.

Smooth Surface - Clean, Professional Finish

This model features a smooth surface with no embossed grooves or markings - a clean, professional finish that suits large wooden boxes, industrial storage, and heavy-duty cases. The smooth chrome surface also provides better corrosion resistance for demanding environments.

Triangle Geometry - Maximum Structural Integrity

The triangle geometry provides exceptional structural strength, with the symmetrical three-way design distributing stress evenly across all three faces. Combined with the 1.5mm thickness, this delivers maximum reinforcement for the most demanding applications.

3-Hole Fixation System

Three mounting holes (Ø4.3mm) deliver secure fixation with minimal installation effort. Compatible with M4 or M5 rivets, self-tapping screws, or spot welding.

Triangle Corner vs. Standard Flat Corner: Which One Do You Need?

When to Choose This Heavy Duty Triangle Corner

You're building large wooden boxes or crates. The 41mm face length provides full coverage for thick panels (15-25mm) - smaller corners leave the edge exposed and vulnerable.

You need maximum impact resistance. At 1.5mm thick and 41g, this corner won't bend or dent under heavy loads. It provides serious protection for heavy equipment and industrial storage.

You want a clean, professional finish. The smooth surface with no embossed grooves provides a refined look that enhances large wooden boxes, industrial cases, and premium storage solutions.

You need reliable reinforcement for heavy applications. The 1.5mm steel provides 3x the thickness of standard 0.5mm corners, making this the triangle corner for the toughest jobs.

Applications

What Are You Using Now?

If you're currently using thin corners or no corner protection on large cases, upgrading to the 7401-41 heavy duty corner is essential - standard corners simply can't handle the weight and impact that large cases experience.

The bottom line: Large cases need large corners. The 7401-41-FE-CR is the triangle corner for heavy-duty applications - providing 3x the thickness of standard corners with full 41mm coverage for thick panels. It's the one-time investment that keeps large cases intact.

Installation & Maintenance

Installation:

• Position the corner against the case edge
• Mark hole positions using the 3 holes as a guide
• Pre-drill with a 3.8mm bit (slightly smaller than 4.3mm for tight fit)
• Secure with M4 or M5 rivets, self-tapping screws, or spot welding

Maintenance & Storage:

• Wipe with a soft cloth and mild detergent
• Do not use thinners, strong acids, or strong alkalis - these damage the plating
• Store in dry, ventilated areas - avoid prolonged damp conditions
