Adjustable Guide Rail system is used for transporting products. The system comprises a pair of parallel conveyor side panels having upper surfaces in a common plane. A conveyor chain is formed as a plurality of rectangular slats having lower surfaces slidable along the upper surfaces of the conveyor side panel. The upper surfaces of the slats function for the receipt of products to be conveyed. The spacers/adjuster slide blocks have central apertures axially aligned therein. A plurality of pairs of parallel oriented adjuster slides is mounted for axial movement above and below the apertures of the spacer/adjuster slides blocks. An adjustor gear with gear key for each pair of slides is formed in a cylindrical orientation constituting a pinion mounted with an aperture aligned with the apertures of the spacer/adjuster slide blocks.
