ARX 4 line bars are Alloy, 25mm OD inc grip and have a Stainless Steel Centre Bush which will take a 6mm Dyneema Chicken loop rope.
Chicken loop (no QR), trim strap and even harness line inc. Please note that the chicken loop is NOT quick release so you would need to unhook to release your kite. You could attach to the chicken loop with a quick release shackle
The end rubbers are breaking up, but can easily be replaced with the X2 type Powerflex bar ends, a set of which I will include with each bar.
