An adjustable rack system has a column with a plurality of teardrop shaped slots and a beam having a connecting bracket that connects the beam to the column. The connecting bracket can be an L-shaped bracket with a recessed portion in one of the legs of the L. A plurality of connectors extend from the surface of the bracket and are adapted for insertion into a large upper portion of the teardrop shaped slots and then moved downward to the bottom portion of the teardrop shaped slots. A locking pin is provided that extends through an opening in the recessed portion and is movable between an extended position where the locking pin projects beyond the recessed portion and a retracted position where the locking pin does not project beyond the recessed portion. A spring is coupled to the locking pin and can be located at least partially within the indentation. The spring biases the locking pin towards the extended position such that the locking pin is biased into the large upper portion of one of the teardrop shaped slots when the beam and column are connected.
