How It Works

The Omni-GWS is designed with two sets of spring loaded steel balls that become dislodged and fall into a transparent dome when subjected
to an impact that exceeds the preset g-level.


Set the spring loaded ball sets with coordinating color using tweezers. When set, screw together the two transparents pieces to create a dome. Adhere OMNI-GWS to product or shipping box, screw it on to a wooden shipping pallet or mount it on mounting plate and screw on to shipping surface.
