Claim:
A drive-in storage rack, comprising: a left side upright and right side upright each having vertically aligned bolt clearance holes; a left side non-inverted L-shaped drive-in rail attached to the left side upright via a left side rail arm; a right side non-inverted L-shaped drive-in rail attached to the right side upright via a right side rail arm, with no member connecting the left and right side uprights, below the left and right side rail arms, to provide an open space between the right side drive-in rail and the left side drive-in rail large enough to allow a fork-lift truck to enter and place a pallet onto the drive-in rails; with the left and right side rail arms each having an upright section including a sidewall section and a rail section, and with the sidewall section substantially perpendicular to the rail section, and with the left and right side drive-in rails resting on top of the rail sections of the left and right side rail arms, respectively; and first and second pairs of circular through holes in the upright section of each side rail arm, with the first pair of circular holes offset from the second pair of circular holes, and bolts extending through the offset holes in each side rail arm and through the vertically aligned bolt clearance holes in the uprights, to reduce or avoid sagging of the drive-in rails.
