Patio bolts are commonly used to secure sliding, hinged, and double doors in residential and commercial applications. They provide added security by locking one door panel in place and are available in a range of sizes, finishes, and fixing styles to suit timber, aluminium, and metal doors. Patio bolts are ideal for French doors, shopfronts, gates, and patio door setups.
