S3 cases are manufactured by Alfred Manufacturing Center in Denver, Colorado, bringing over 75 years of manufacturing experience.

S3 Cases are proudly developed and manufactured in the United States of America.

As of 2021, there are 11 distinct S3 Case sizes available. We continue to develop new designs and sizes of hard-sided cases added yearly.

All S3 cases are available in 5 colors: black, blue, clear, red, orange and yellow. Custom colors can also be developed with a minimum order

S3 Cases come in 11 distinct sizes. Please take into account the inner and outer dimensions of our cases with 1 to 2 inches of foam around the case to protect your equipment. Highly sensitive equipment should allow for even more outer foam.

Alfred Manufacturing developed the S433 resin specifically for S3 Cases. The resin is a polypropylene based material that has been specifically enhanced with performance additives to increase impact resistance, toughness and dust resistance. The S433 resin has been engineered to perform in the harshest of environments, making these great industrial, medical and military grade cases.

Changes in altitude pressure and geographic location can create a vacuum that effectively seals watertight cases shut. S3’s purge knob valve equalizes the pressure within the case to make it easier to open. Once the air is equalized by twisting the knob to the left, make sure you screw it tight to the right so it’s sealed shut.

S3 Cases can be purchased with foam or without foam. Our T1000-T4500 cases have an optional form fitted liner, and our T5000-T6500 have polyurethane block foam that is 100% customizable/pre-scored.
