Pull Up Bars

How to avoid the pull up bars falling to the greatest extent?

1. If you choose a punch-free pull up bars, be sure to choose a pull up bars with rubber pads on both sides of the pull up bars, which will have the greatest friction with the wall or door frame.

2. The fixed position of the pull up bars should choose a solid wall or a door frame. The door frame of some rooms may be hollow inside. It should be reminded here that if it is fixed on the door frame, it will definitely cause deformation of the door frame for a long time-fixing the position of the pull up bars There is a slightly sunken pit, but my house is an old house, so it doesn't matter.

3. This is also the most important point. When fixing the pull up bars, the length of the pull up bars is adjusted by rotating the pull up bars, so as to tightly press against the wall or door frame. When using the pull up bars, many people ignore the fixing direction of the pull up bars. It is said that counterclockwise is to lengthen and fix, and clockwise is to shorten and disassemble. When grasping the pull up bars, both the forehand grasp and the backhand grasp will form a force that rotates from top to bottom, and the rotation directions of these two forces are exactly opposite. , we must choose the correct grip direction, here is an example of my indoor pull up bars:

When I need a forehand grip, I need to be outside the bedroom door, and the forehand grip will have a top-to-bottom force that makes the bar tighter and tighter.

But if I am in the bedroom, the forehand grip also has a top-to-bottom force, and the direction of this force is opposite to the forehand grip force outside the bedroom door, which will cause the pull up bars to shorten and fall off when I use it.

When I need a backhand grip, I need to be in the bedroom, so that the top-to-bottom force of the backhand grip makes the bar tighter and tighter.

Likewise, if I use a backhand grip outside my bedroom door, the top-to-bottom force is reversed, causing the bar to shorten and fall off during use.

4. When choosing a punch-free pull up bars, there used to be only this very simple pull up bars (Figure 7), but now various brands have also made some optimizations and upgrades (Figure 8), the contact wall area on the left and right sides has increased, Compared with the previous very simple pull up bars, the friction force will be greater, so the pull up bars with a large contact surface with the wall is given priority when choosing.

Lastly, we strongly recommend our new design--pull up bar supporters DF-N5 to double ensure your safety.
