This field-deployable folding crate is just as sturdy and useful as the trusty milk crate it’s modeled after, but folds flat and snaps back to attention when duty calls. Because, if there’s any downside at all to the sturdy, time-tested milk crate, it’s that there’s nothing to do but stack them up when not in use – taking up a lot of space. Sides lock securely together when needed. Sturdy polypropylene construction is much stronger than the cheap plastic versions found in discount stores. Sized to carry 4 gallons of milk, equal to 50 lbs. of tools, rope, cords, fasteners or other essential “junk.”
