You have a 4 line kite (not a depower), so you have to use a bar which is ment to modificate a 4 line kite, which is originaly sold with handles.
There are 2 ranges:
simple and cheap: for trainer kites, no chicken loop, only kite killer
advanced, expensive: kite should fly even better than with handles (Ozone Turbo bar for instance- I'm waiting to reiceve it in a couple of days)
this Turbo bar and similar come without lines, not so sure for ordinary 4 line kite bar. (If the description is talking about depower straps or clits, then you are obviously looking at a wrong bar. It's for depowerable kite)
