The MORryde CTG80-3672-2DW cargo slide tray does not come with a universal hardware kit because the correct screws or bolts depend on your RV's compartment floor and mounting surface. Typically, installation requires multiple fasteners securing both rails, with rail holes accommodating hardware up to about 5/16" in diameter. Before installation, verify there are no wiring, plumbing, or tanks underneath the mounting area. It is advisable to consult an RV technician to select the appropriate fastener type and length based on your specific RV coach. For detailed installation guidance, you can refer to the MORryde cargo tray installation guide available on Elkhart RV Parts' website.
