Horizontal bars with spacers

Spacer

— simulators fixed between two walls or other supports, however, not by bolts (like traditional inter-wall models, see the relevant paragraph), but by stops that press against the supporting surfaces with force and do not allow the projectile to move under load. Only horizontal bars are made spacer (see "Type"). The advantage of this option is simplicity and versatility: the structure can be easily made sliding to adjust to different distances between the walls, and for installation it is enough to place the horizontal bar between the supporting surfaces and use the stops. At the same time, the reliability of such fastening is noticeably lower than that of the interwall fastening, moreover, it strongly depends on the type of surface with which the stops are in contact. Therefore, this option is recommended only for athletes with a relatively small body weight.
