ZUMRO’s Shelter Model 311 utilizes the same principles of compact design and rapid deployment as our smaller shelters, but it provides a substantial 311 square feet of floor space.  It excels in applications that require more under-shelter area than our compact systems provide such as rehab, business continuity and triage.  Despite its exceptionally usable and flexible footprint, the Shelter Model 311 weighs only 230 LBS and deploys in under 4 minutes with only 1 or 2 operators.  No other shelter can provide this much area so quickly and in such a small, lightweight package.
