Thermodyne’s ShokStop case is built tough with a rugged military-grade, shock absorbent polyethylene shell that reduces impact and steers shock away from your delicate equipment. While injection molded cases are rigid and transfer much of this impact internally, the ShokStop’s outer shell flexes to absorb and dissipate harmful impact, sparing your gear from the tortures of travel. So even when the baggage handler tosses your case across the tarmac, the resilient ShokStop shipping case will stand strong under pressure and shield your equipment.
