INSTALLATION
This sturdy, steel rack mounts securely to the rail of your open utility trailer. Determine where on your trailer rail you want to place the racks. The towers should be approximately 3 feet apart. Then attach the pre-drilled towers with Grade-8 bolts and nylon insert lock nuts (not included) to the rail of your open trailer. You will have to drill holes in your rails to mount racks. This rack system is not designed to be welded to your trailer. Be sure to face the rack toward the outside of the trailer for easy access to your trimmer. This configuration also leaves the bed of your trailer open for lawn mowers and other landscaping equipment. Mounting Trimmers: To use the rack, simply place your trimmer horizontally in the hooks. The hooks on one of the towers have integrated steel hasps. To secure your trimmer to the rack, just fold the hasp over the trimmer and lock in place with your lock.
