Drive-in storage racks may be configured to fit within almost any storage area. Racks may be furnished to hold trucks only a single unit deep or up to 6 trucks deep. Heights are determined by the product to be stored and by the clear height of the ceiling. Storage lanes are generally engineered to store tables 72" long/diameter or 96" long. Chair trucks may be stored in separate drive-in lanes or in the same lanes used for 72" diameter banquet tables. Trucks stored above the floor level are supported from their ends by continuous rails that run the full depth of the system. Rails have side guides to ensure proper alignment when storing table and chair trucks.
