A pallet gap filler for a pallet and a lift is provided. The pallet gap filler includes filling and engaging elements. The filling element is insertible into a portion of a space defined between tines of the lift and one or more of top and bottom decks and blocks and/or stringers separating the top and bottom decks of the pallet. The filling element is configured to assume a first configuration during filling element insertion and a second configuration in which, following filling element insertion, the filling element fixes relative orientations of the pallet and the lift. The engaging element is actuatable with the filling element initially assuming the first configuration to cause the filling element to assume the second configuration.
