Grasp one of the straight top wires with the flat nose pliers in the center of the bar (1/2”) and bend upwards 90°.
Note: - This upwards wire will not be quite central to the bar.
Measure 1/8” from the bend and make a 45° bend away from the center.
Grasp this bend with the round nose pliers and form a medium loop, then bend the wire downwards 90° and trim to 1/8”.
Grasp the bar in the flat nose pliers as shown and wrap the loop closed 3 times. Trim and tuck the end in.
Check all is straight and adjust with the nylon jaw pliers if necessary. Notice how the bar looks a little bit like a coat hanger at this point!
