Zedlock gate lock claims to be more secure than conventional devices like padlocks and chains at a comparable cost. It cannot be cropped by bolt cutters (the most common method of forced entry) and the stainless steel sliding bolt cannot be cut by a gas torch.
Zedlock comprises a sliding bolt and deadlock, with the long throw making it suitable for field gates where the gap between the gate and gatepost is up to 50mm (2in). The lock mechanism is a Union five-lever deadlock and the locks can be offered keyed-alike so one key can operate all of your farm and estate gates. You can add locks at a later date which are opened by the same key, too.
Three versions of Zedlocks that suit wooden and metal gates are now available directly from zedlock.com, priced at £65+Vat. They are also available at branches of McVeigh Parker.
