The "XH" stem extension is a simple and effective design option for installations where pipe insulation would make standard handles inoperable. The stem extension can also be used where a handle needs to be raised above an obstruction. Combining this feature with the added security of the "LD" locking handle gives you the "XLD" locking stem extension handle. The "XLD" handle offers the end user the security of a pad lockable handle and can be locked in either a fully open or closed position. These handles are available for use on all bronze ball valves and are just one of the many options and accessories offered on this line of valves.
