Quickly designate no-go areas or hazards with the Guardian Expandable Steel Crowd Control Barrier with Locking Wheels. Constructed of steel with black and yellow accordion slats for visibility, it has four locking casters and handles on both sides allow you to transport and position it where needed. The wheels lock into place to keep it from shifting while in use. When expanded, the 44” H x 16” D barrier measures 8’ 10.5” W x 16” D. When it’s no longer needed, it collapsed down to17” W for compact storage and easy transport. Lightweight at only 36 lbs., it’s a highly portable solution to crowd or vehicle control in temporary situations such as public events or thoroughfares, warehouses, job sites, and more. Two wrenches and pillars are required for assembly, and it comes with a set of mounting brackets and hardware. Multiple units may be ganged together with the built-in male/female pin connector system to create desired length as needed.
