This XFORT front door chain is designed to improve your home security by limiting how much your front door opens, allowing you to identify a caller before fully opening. It features an easy-release mechanism and a strong, durable construction made of solid steel to resist forced entry. The chain is finished in a pristine polished chrome, complementing other door furniture, and its narrow design allows it to fit any door type or size. Installation is straightforward as it is completely surface-mounted and comes with all necessary fittings, including color-matched screws. This door chain is primarily for front doors but can also be used on internal doors for enhanced safety. It is available in polished chrome and polished brass finishes to match your home decor.
