LokkBolt™ is a high-quality, heavy duty drop-bolt for retaining and securing driveway and other residential or commercial gates. The housings are made of tough, rust-free polymers and the bolt is made from superior 316-grade stainless steel. The LokkBolt comes in two lengths – 450mm and 610mm – 18 and 24 inches- to suit different styles and sizes of gates. An optional ‘Base Plate’ helps retain the bolt into the ground surface and provides a neat, stylish finish.
