STRONGHOLD

Rugged and Robust Rotationally Molded Cases

Overview

STRONGHOLD cases provide the ultimate protection in the most rugged terrain. These cases are double-walled and constructed from polyethylene.

Toughest Case Available on the Market

These cases are rotationally molded. That means thicker corners and stress free walls making this the strongest case you can buy. This case has been used by the US military, all around the world, in all types of conditions. All hardware is stainless steel, and each case comes standard with a pressure relief valve.

Stackable and Interlocking

STRONGHOLD cases feature a unique arrow design on the lid and bottom. This feature allows the cases to be stacked and interlocked together.

Many Color Options

Gemstar stocks colorant for 100's of colors which makes producing custom colors fast and easy. Consider using custom colors for safety or branding purposes.

High Quality and Guaranteed for Life

Quality is important to us. That’s why we make our cases in Minnesota. It’s also why we stand behind every one of our cases. Every case we manufacture is guaranteed for life.
