Stake Wall Model Containment Berms feature a unique design which allows the sidewalls to collapse in either direction and spring back automatically to their upright position! Roll drums over the sidewalls, drive trucks through them, and the sidewalls always return to vertical without assistance. No set-up required - unfold and the sidewalls automatically spring into their vertical position. Custom sizes available. Vertical sidewall supports located every 12". Each Support features a built-in "living hinge" at its base, which allows sidewalls to collapse in either direction. Collapsed sidewalls spring back automatically. Meets SPCC and EPA Container Storage Regulation 40 CFR 264.175.
