Pallet rack lock

A rack lock in a pallet rack system releasably locking one end of a shelf beam of a pallet rack to an upright column of the pallet rack, said column has a plurality of vertically spaced locking apertures, said rack lock including;

• a lock plate fixed to the shelf beam and positioned substantially parallel to the upright column, a load bearing stud fixed to the lock plate, said load bearing stud positioned in a lower portion of a locking aperture, a resilient carrier having one end fixed to the locking plate and the opposite end being free, a lock stud mounted on the resilient carrier and movable therewith, said lock stud positioned in an upper portion of a respective locking aperture to prevent upward movement of the load bearing stud in its locking aperture, and a dog limiting movement of the resilient carrier away from the lock plate, whereby the lock stud may be selectively moved out of its locking aperture by bending a portion of the resilient carrier away from the lock plate and the dog limits bending of the resilient carrier sufficiently to prevent permanent deformation of the carrier.
