No threading of wire is necessary. The wire is slotted in from the side. The top section of the lock is hand tightened to secure the cable on to the valve. The Pro-lock is then slid along to the optimum position, much like the knot of a neck tie, then locked onto the cable using the Pro-lock Operating Tool.
Pro-Lock is the ideal solution, used with padlocks, for remote unmanned locations to prevent vandalism and theft from pipelines and vessels. It is ideal for electrical switchgear and is the only solution to uniquely lock each isolated item. It can be used in addition to most lockout systems; however the Pro-Lock system is the only system which is capable of being used with or without a padlock.
Pro-Lock fits most types and sizes of valves. It is cost effective, lightweight and durable manufactured of stainless steel & Polypropylene. Pro-Lock is available in 3 colors with matching multi-stranded galvanized steel PVC coated wire to enable easy recognition of locked open or locked closed valves
It can be used in conjunction with write-on security seals for detailing isolation details.
Pro-lock has an enormous range of possible applications - on construction sites, in industrial environments and, of course, in the offshore and petrochemical industries.
Easy to use, reliable and extremely hard wearing, Pro-lock is one of the most effective and versatile lockout systems currently available. For maximum security applications, the most cost efficient lock-off combination is Pro-lock, galvanized steel wire, and a numbered security seal. Isolation details can be written on security seal, thereby eliminating the need for high cost labels.
