Features : 1. Our floor door guides are fully adjustable and compatible with sliding doors, allowing you to keep your stable cage running for years. 2. Smoothly and quietly moves the door backwards. This is an improved sliding door floor guide. It is adjustable and can fit door leaves from 30 mm to 84 mm. With this stick you do not need to drill holes in the floor or cut a width in the bottom door, where it is much easier to install a sliding door. 3. This installation of the floor guide for stabilising the door keeps the door from moving away from the wall. Therefore, you never have to worry about the door or the roller guides when the screws come loose. 2. Roll up the guide on the floor, making sure there is enough room for the door, is enough to accommodate the film inside, then tighten the screws at the bottom of the guide. Material: carbon steel. Colour: black. Adjustment instructions: 1. There must be a distance of 0.95 between the floor and the floor of the door. 2. The guide is fully adjusted to the floor (if necessary). 3. If it touches the wooden floor, a felt pad should be considered.
