Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to open cable ties [title] Find the locking mechanism. [step] If you look at a ready-to-use cable tie, notice that one end tapers to a point, while the other is capped with a tiny cube. When used, the pointy end is fed through a slot in the cube to form a loop and then pulled tight.

Ending1: The cube is the locking mechanism that keeps the tie from worming back out through the slot, so look for that. [title] Bend the tie's loose end back. Ending2: Doing this typically only takes half a minute, but it can also take up to a day, depending on the size of the cube. [substeps] Look for a locking mechanism that has small cubes on it. Ending3: The cubes often have individual locking mechanisms and may be located at random. [substeps] The locking mechanism used on most new cable ties will be located toward the top of the square-shaped end of the cable tie. Ending4: This allows some of the dead cable to pass through so that the two ends of the cord each remain separated. [title] Use a nut if the locking mechanism is plastic or sturdy.
