Gift Box Corner Protector 35mm Chrome Plated Small Case Hardware

Triangle Corner Protector for Small Cases - 35mm Chrome Plated 3 Holes

What Makes This Triangle Corner Protector Different

Largest Coverage in the Triangle Series

At 35mm face length, the 7401-37-1-FE-CR offers the largest coverage in the triangle corner lineup. It provides significantly more edge protection than 22mm or 28mm models while remaining compact enough for small cases. This makes it ideal for boxes and cases that need substantial corner reinforcement without moving to standard flat corners.

Embossed Groove - Decorative Accent

This model features a single embossed groove on one face - a subtle decorative detail that adds visual interest without overpowering the design. The embossed groove creates a premium look that enhances jewelry boxes, gift boxes, and cosmetic packaging with an antique or vintage aesthetic.

Balanced Weight - 15g with 0.7mm Thickness

At 15g with 0.7mm thickness, this model offers more substantial protection than thinner 0.5mm models while remaining lightweight. The 0.7mm steel provides better impact resistance for larger cases, making it ideal for boxes that need extra reinforcement without the bulk of 1.0mm+ corners.

Triangle Geometry - Clean, Professional Finish

The triangle geometry provides a clean, balanced appearance that complements small cases and boxes. The symmetrical three-way design distributes stress evenly across all three faces, ensuring consistent reinforcement on every side of the corner.

3-Hole Fixation System

Three mounting holes (Ø4.2mm) deliver secure fixation with minimal installation effort. Compatible with small rivets, self-tapping screws, or spot welding.

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

When to Choose This Embossed Triangle Corner

You're building medium to larger small cases. The 35mm face length offers substantial coverage for boxes that need more reinforcement than 22mm or 28mm models provide, without jumping to standard 35mm+ flat corners.

You want a decorative accent. The embossed groove adds visual interest - perfect for vintage-style jewelry boxes, antique-look gift boxes, and premium packaging that demands attention to detail.

You need more protection than thinner models. At 0.7mm thickness and 15g weight, this model offers better impact resistance than 0.5mm corners while remaining lighter than 1.0mm options.

You're working with medium-thickness panels. The 0.7mm thickness and 4.2mm mounting holes are designed for panels that need more reinforcement than ultra-thin options provide.

Applications

What Are You Using Now?

If you're currently using no corner protection or plastic corners, upgrading to steel chrome corners is one of the lowest-cost ways to significantly improve your product quality perception and reduce corner damage returns.

The bottom line: A chrome steel corner is a one-time investment that pays for itself in fewer returns, higher customer satisfaction, and a more premium product image. At under $1 per corner, it's the smallest cost that makes the biggest visual difference.

Installation & Maintenance

Installation:

• Position the corner against the case edge
• Mark hole positions using the 3 holes as a guide
• Pre-drill with a 3.6mm bit (slightly smaller than 4.2mm for tight fit)
• Secure with small 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
