rounded tip.
It would probably be advisable to “mock up” the system on a board with its
dimensions marked as a perimeter. This will allow you to cut the tube to the proper length,
and bend it as needed to go through the cycle without interference. Adjust the length such
that the reshaped screw slides through the metal insert guide into the door panel, and
travel won’t try to drag the assembly over the metal insert.
A relatively light tension spring should be used, located to provide a closing torque
on the handle. The end of the spring can be tied to the wall of the latch.
cabinet, and a little dry micro will seal the ends of the wires to avoid scratching
yourself in the future. A heavy spring is not necessary, as the system will “center over”
in the full closed position, and a theoretically infinite force at the end of the latch will not
overcome the spring to unlock the system. With the rigidity of the tubes, a mere visual
look at the handle will ensure that the locking screws have been pushed into place (if the
door is anywhere near closed.
This latch system requires one to be aware of holding the handle in the fully open
position when closing the door, to avoid damaging the paint around the door opening.
Neither the two place system nor the 4 place system, as designed, can be closed. without
damaging the paintwork and the perimeter of the door.
