Our Simple-Lock™ crates with 68 sizes stocked in 6 inch intervals offer a strong yet lighter engineered alternative to standard shipping crates. Our Simple-Clip™ crates offer a high-strength, heavier-duty reusable/returnable option. Both crate styles assemble easily without the use of power tools or nails, ship and store flat, and are reusable. Our crates are available with integral pallets, without pallets, or with heavy duty skids. Heavy duty skids are also available for purchase without a crate.
