The CLOCKBOX ensures that no unauthorized person is tampering with your irrigation controller—and will also protect it from being stolen. At 14x17x10 in, the unit fits most outdoor irrigation controllers. It is powdercoated hunter green, and features a removable front cover for access. Its locking mechanism consists of two security 0.5-in. hex-pin locking bolts, and includes two unlocking bits—one for the owner, and one for the irrigation or maintenance technician. It can be installed in less than 20 minutes.
