Enhance your Ring Wired Doorbell Pro 3rd Gen Retinal 4K installation with this precision-engineered 1-inch mounting spacer. Crafted from durable PETG material with UV resistance, this spacer provides the perfect solution for optimal doorbell positioning. The spacer features perfect alignment with your doorbell's mounting holes and can be installed on any side of the door. Installation is straightforward - simply use the mounting screws that came with your doorbell, no additional hardware required. This spacer measures approximately 5.37 inches in height, 1 inch in width, and 1.43 inches in length, providing ideal spacing for your doorbell installation. Please note that this spacer is not stackable and is specifically designed for the Ring Wired Doorbell Pro 3rd Gen Retinal 4K model only - it's not compatible with Ring PRO series, battery-powered Ring doorbells, or Ring OEM corner kits. The package includes one mounting spacer (doorbell and bracket not included). The screwdriver-friendly design ensures easy installation, though care should be taken not to overtighten.
