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.
