Another most important advantage of this design is that the rollers are the most wear, and at the same time, the most easily replaceable part of the entire input mechanism. Thus, during the first breakdown, it is very easy to restore the performance of the entire opening system as a whole. At the same time, sliding mechanisms are capable of blocking the barrels of any length — in this they are unsurpassed, and there is no other type of opening mechanisms that would suit very wide spaces. If you need to block the completely non -standard space, you can use sliding sliding gates in which two canvases converge on rollers to each other, tightly closing the entrance.
