All Boxlok products are designed as a centering device. These units should only be used inside the valve box or another generally accepted unit to achieve operating nut access on the valve.

The Boxlok is not to be used in a situation where a vertical load is placed on the Boxlok. This will cause the unit to bind the operating nut.

If you have specific questions about the use of the Boxlok,
please contact Customer Service @ 1-615-210-9141.
