I have recently upgraded to 75mm box section from 60mm box section. I had done my research and expected these to be meaty but first impression out of the box none the less - other than being well packed was 'monster'! Even at a body weight of just over 100kg, the 200kg recommended limit is more than enough and I like that the bar has built in various dipping width options for different sized users. This is ensured by were you place your hands on the bar yet without the handles being too far away from from parallel from each other like some angled dip bars can be. This is because of the good design and sheer genuine commercial size of the attachment meaning the needed angle is not too steep. My only minor gripe is that the half way point on each handle (seeming these are variable width) doesn't have a clear marker. This would have been a nice touch for ensuring equal judgement and consistency. However, this is an easy fix with either a silver sharply or some electrical tape that can be replaced, renewed or removed as needed. All in all these are bulky but tough, built to last and a good add on to your rack for the money there is no doubt. Thanks strength shop.
