String ladders are held in place by a metal crimp attached at the top. This crimp is inserted through the opening on top of the tape roll.
- Remove the crimp through the wider opening to release the string ladder.
- Move the crimp or adjust it by tying a knot in the ladder. Other crimps are also available to change the position.
- Replace the crimp or knot in the opening on top of the tape roll, then secure it by moving it to the narrow opening.
