To Product description:
The manufacturer of this chin-up bar is from England and is called "Innovation Fitness". The pull-up bar pictured here at Amazon is the predecessor ("Powerbar 1"). The successor model ("Powerbar 2") is improved: the ends of the strap has been improved so that they no longer press against the wall and the rubber pads have been improved, so that the bar will not cause damage to the door frame. I would contact the seller before buying to ensure that it delivers the successor and not the previous model!
Benefits of this chin-up bar over other door bars:
(1) Because the rod is not clamped in the door frame, there is also no risk that distorted the doorframe. (2) Because the rod is resting firmly, is compared to a normal door bar is less risk that the rod from slipping. (3) Since the bar has a height of about 2.10 meters, you can - in contrast to IronGym - convenient pull-ups as well as the exercise "legs lifting the Hang" run. (4) In addition, one would, if the Stage would ever solve, landing on his feet and not on the back - and I prefer to sprain my ankle when I break my spine.
For the dimensions:
The height of my door frame (measured to the upper edge) is 2.17 m. The bottom of my door frame is 15.3 cm. If I Immersion the pull-up bar in the door, the upper bar (the bar where you do the exercises) has a height of 2.10 m. I'm 1.80m tall, I have just a little bend at this height the legs. So I can easily do chin-ups next to the abdominal muscle exercise "legs lifting the slope". The upper part of the door frame can according to the description a height of up to 8 cm (the upper part of my door frame has a height of 7 cm and it fits easily), I think - according to its own measure - that 9 cm maybe still just as possible (which also depends a bit of the frame depth). The frame depth can be up to 21 cm per description - according to its own measure it really involves the maximum possible value. The contact surface of the upper part of the door frame (for ironing the pull-up bar) should be at least 1 cm - create a larger area than 1 cm but not necessary. The inside width of my door frame is 68.5 cm - narrow should not be the internal width, because the strap pull-up bar at a distance of about 68 cm. The maximum inside width of the door frame should be according to the description 85 cm, as the chin-up bar has a width of 91 cm - that would be so 3 cm pad left and right of the chin-up bar; I find better but 5 cm pad left and right, which would only allow a door frame width of 81 cm.
For processing:
The chin-up bar is very solid processed and well painted. There are two rubber parts mounted on the rod, which can be shifted according to the door frame and thereby prevent the door frame is damaged (should these parts ever go broke, you can also bike handles about it strips); They also rub off in any way. The bracket each have a small rectangular sturdy plastic frame, which fits perfectly to the upper door frame and therefore no longer pressed against the wall! The often criticized problem that the bracket can press against the wall and damage the wall is so resolved - if the bearing surface of the upper door frame is at least 1 cm high, the temple no longer touch the wall! Regarding stability: I weigh only 67 kg and the bar keeps natural rock solid. So how much the rod can withstand I can not judge, but have the impression that the door frame rather collapses as these processed solid rod is damaged.
