8 Different Mounting Options: Our sliding door guide is fully customizable with 8 configuration options. Simply attach your sliding door with the right configuration. Floor Mounted and Recessed with Support: No need to drill holes in the floor, our sliding door guide roller kit is specially designed to allow the bottom door mount to remain completely flush with the floor, for a quick and painless installation. Combined with the countersunk holes, the flat head screws sit flush with the mount, avoiding protrusion and rubbing against the sliding door. Fully Adjustable: 8 configuration options easily adjust for a perfect fit. Fits all sliding doors up to 8.4cm thick. Regardless of the size or type of sliding door, this floor guide will provide a secure fit. Easy Installation and Adjustment: Attach the guide to the wall trim just outside the opening with the longest plate touching the floor. Our included easy-to-use installation manual will guide you step-by-step to easily install this sliding door guide. With two small steel wrenches, adjusting the lock nuts on the floor guide roller after mounting it on the wall becomes very easy. Scratch Protection: By adding 2 extra screws, you protect the door's floor guide for increased security.
