Ergonomic design provides 100% inside berm accessibility with an unobstructed side-to-side floor space for vehicle tires, foot traffic, and cleaning.

• Single-piece construction - patented Rigid-Lock wall-support system integral to berm provides unobstructed work space
• Quick and easy setup - no assembly required
• Durable EnGuard™V, modified PVC coated fabric withstands long-term UV exposure

Exceptionally strong structural integrity includes a reinforced CriticalCorner™ design featuring wraparound diagonal radio frequency welds to prevent billowing, unwrapping, or sagging of the corners during full containment for fluid-tight reliability

The built-in Rigid-Lock wall supports maximize usable space inside the berm and greatly reduce any tripping hazard on the berm perimeter. The device only folds down one way, inward towards the inside of the berm. The one-piece design folds down flat and remains integral to the sidewall. Supports resist extreme temperatures (-50 to 160° F). When in the down position, they can withstand vehicle weights in excess of 11,000 lbs (5,000 kg) at each tire.

Sidewalls lower quickly for easy drive-in and out. Portable design folds down quickly for storage and transport.
