Lightweight Rounded Corner Protector 35.5mm Chrome Plated 3 Holes

Lightweight Rounded Corner Protector for Small Cases - 35.5mm Chrome Plated 3 Holes

What Makes This Lightweight Rounded Corner Protector Different

Ultra-Lightweight - Just 11g

At only 11 grams with 0.4mm thickness, the 7510-FE-CR is the lightest rounded steel corner in the NRH lineup. Eight corners add just 88g to total case weight - making it the ideal choice for air-shipped products, lightweight designs, and applications where weight is critical. The ultra-thin material provides adequate corner reinforcement without adding unnecessary bulk.

R15 Rounded Profile - Smooth, Snag-Free Protection

The 7510-FE-CR features a smooth R15 rounded profile that eliminates sharp edges and corners. This design prevents snagging on equipment, clothing, and surrounding items during transport and handling. The smooth radius also reduces stress concentration points that can lead to cracking.

35.5mm Side Length - Compact Coverage for Small Cases

With 35.5mm side length, this corner provides just the right amount of coverage for small to medium cases. The compact size ensures that edges are protected without looking oversized on smaller boxes and cases.

Chrome Plated Finish

The chrome plating provides corrosion resistance, surface hardness, and a bright, professional appearance that enhances the look of any case. The smooth chrome surface is also easy to clean and maintain.

3-Hole Fixation System

Three mounting holes (Ø3.3mm) deliver secure fixation with minimal installation effort. Compatible with small rivets, M3 self-tapping screws, or spot welding.

Rounded Corner vs. Standard Corner: Which One Do You Need?

When to Choose This Ultra-Lightweight Rounded Corner

Weight is critical. At just 11g per corner, this is the lightest rounded steel corner available - ideal for air-shipped products, lightweight designs, and applications where every gram counts.

You need smooth, snag-free edges. The R15 rounded profile eliminates sharp corners that catch on equipment, clothing, and surrounding items. Perfect for small cases that move through tight spaces.

You want a refined appearance. The smooth rounded profile and chrome finish provide a professional, premium look that enhances small cases and lightweight packaging.

You're working with thin panels. The 0.4mm thickness and small 3.3mm mounting holes are designed for thin materials where standard corners would be too heavy or cause splitting.

Applications

What Are You Using Now?

If you're currently using plastic corners or heavier steel corners on lightweight cases, upgrading to the 7510-FE-CR provides the same smooth, rounded protection at a fraction of the weight.

The bottom line: The 7510-FE-CR is the lightest rounded steel corner available - providing the protection of steel at nearly the weight of plastic. At under 100g for eight corners, it's the smart choice for lightweight cases and air-shipped products.

Installation & Maintenance

Installation:

• Position the corner against the case edge
• Mark hole positions using the 3 holes as a guide
• Pre-drill with a 2.8mm bit (slightly smaller than 3.3mm for tight fit)
• Secure with small rivets, M3 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
