This advanced design is another Fredlov method of saving
money for the user, it can easily be installed on all existing test heads
that utilize the spud. Not for multiple cylinder test heads.
The spud stem is protected from damage resulting from
hitting the cylinder collar or contact with the floor or bench when
closure is set aside.
This leaves hands free and provides simple guidance into
the test vessel once the cylinder is inside the test vessel
The closure guide is also manufactured in stainless
steel to meet unique customer requirements
