The Hera Ray Bee Door Knocker is fine jewelry for your home. Using the lost-wax casting method, delicate details of the flowers and bumblebee are beautifully preserved. It is secured through the door with bolts, fastened internally using decorative bolt caps. The method offers the most secure fixing, supports the weight, and helps prevent removal from the outside. Installation on PVC, composite, timber and metal doors are suitable. All bolts and caps are provided along with an installation template.
