Doorway horizontal bars

For doorway

— exercise machines that are mounted on a standard doorway — and, usually, without any additional work like drilling walls. This category mainly includes horizontal bars (see "Type"). Such a horizontal bar has a set of special stops: when installed, one of them clings to the upper trim of the doorway on the opposite side of the crossbar, and the second rests against the wall from the side of the crossbar. Due to this design, installation is very easy and fast, literally in a matter of seconds. This is especially true in light of the fact that a horizontal bar suspended in the doorway would interfere with the closing of the door: the projectile can only be hung up during training and removed after it. And some models of "door" horizontal bars can also be used on the floor, for example, for twisting on the press. There are two main drawbacks to this option. Firstly, such an installation is designed for a standard doorway size and an average (plus or minus) wall thickness; in a wide opening, with too thick or thin walls, hanging may not be possible. Secondly, the reliability of hanging the horizontal bar strongly depends on the strength of the casing and its fastening. Therefore, before buying a “door” projectile, it is imperative to clarify whether the intended installation site is suitable for it.
