Three case families cover everything from heavy double-walled shipping shells to lightweight, fully custom carry cases, every one ready for an Impact-built interior.
American made in Cannon Falls, Minnesota
// STRONGHOLD® · ROTOMOLDED, DOUBLE-WALLED
Built rugged.
Ready to integrate.
Built to Survive
Cases molded for the harshest field, transport and depot conditions, engineered to demanding industrial and military standards.
Robomold® Process
A precision rotational-molding technology that widens design freedom and cuts environmental impact. Cleaner cases, fewer compromises.
Backed for Life
Every case carries an industry-leading warranty, giving you long-life reusable protection that pays back over years of service.
Three case families
that fits the mission
Stronghold
Rotationally molded with seamless double walls, Stronghold is the heavy hauler of the range: watertight, airtight, and built as a long-life reusable shipping container. When a payload has to arrive intact after years of rough transit, this is the shell that carries it.
RoboRack
Double-walled 19" rack transport produced with Gemstar's precision Robomold® technology, so it stays stackable, airtight and watertight, with the rigidity to protect deployable electronics on the move. Shock-mount the frame, load the gear, ship it anywhere.
Sentinel
Injection molded for a refined, lightweight finish without giving up the seal. Watertight, airtight, and fully customizable, it is the carry-and-present line for instruments, kits and sensitive gear that travels in style.
Molded with precision, sealed tight.
Robomolding is Gemstar's investment in next-generation rotational molding, a process that expands what a single shell can do while trimming material waste and energy use. The result is a cleaner, more consistent case with the seamless, double-walled integrity that makes Gemstar shells watertight and airtight by design.
