Simple-Lock™ Crates

An engineered, nailless alternative to the common wooden shipping crate.

Made in the USA, our Simple-Lock™ nailless wooden shipping crates are lighter, stronger, and easier to fill and assemble than your standard cleated crate. This engineered design is prized in the global market for its durability and efficiency. Crates, pallets and skids can be heat treated to ISPM 15 standards.
