The Bulldog GR250 is a heavy-duty security solution designed to protect garages, workshops and commercial storage areas. This versatile lock is suitable for a wide range of applications, including double doors, sliding doors, gates and standard storage containers.

The unit is constructed for durability, featuring a 3mm cover plate and 5mm mounting brackets for structural integrity. The lock cylinder itself is specifically engineered to be drill and pick resistant, ensuring high-level security for high-value assets.
