The Habonim spring loaded locking device (LD) is ideal for applications where it is critical to keep the valve position without the risk of accidental operation. The locking device fits easily to the valve stem by simply removing the stem nut and threading the lock stem above the handle. The LD can lock the valve in closed or open position. The LD can be fitted to the valve in-line. Available in sizes 1/2" to 2".

While lifting the lock housing above the stop pin (1) turn the wrench (2) to its new position. When the handle is in its new position release the housing to fit on the stop pin (3).
