The incredible Series 20 Orbit Block(TM) is capable of loads up to 250kg (550lb) while weighing a mere 9 grams, only 4 grams heavier than the Ronstan Kite Block yet it can handle 100kg more load!
The main benefit of this pulley is if the wheel were to fail, you do not loose control of your kite because your pulley attachment line runs through the HUB of the bearing and acts as a backup, you can see how this works in the detailed pictures below.
