An anti-tip mechanism for a mobile storage system. The system includes movable carriages, each having a pair of wheels journaled to the carriage frame, and adapted to be moved along tracks on a building floor. The anti-tip mechanism includes a pair of catch rails adjacent to and co-extensive with the tracks. Each catch rail includes an upper horizontal portion projecting toward the track, supported by an upright support member. Two hook plates are spaced apart and attached to the carriage frame for each of the catch rails. Each hook plate has a lower leg projecting beneath the top horizontal portion of the respective catch rail. The attachment of each hook plate to the carriage frame is via an L-tab, which has an insert portion inserted into a slot in the hook plate and a slot in the carriage frame, and an overlay portion overlying the hook plate. The overlay portion is attached to the carriage frame over the hook plate by any suitable removable attachment, such as a threaded fastener.
