What We Like About the Pinnacle Folding CribFoundations Steel Cribs are made specifically for commercial use. They are constructed of heavy-duty steel utilizing a 360 degree welding process to ensure durability. The non-porous easy to clean powder-co ated finish resists corrosion and scratches. These cribs also feature reinforced locking floorboards and oversized locking casters made of non-marking material for easy transport over any surface. Cribs meet CPSC and ASTM crib safety standards and th e new CFR 1633 fire standards. All instructions are printed in English and Spanish and are permanently affixed to avoid loss. Cribs arrive fully assembled and can fold flat in seconds. Full one-year warranty included.
