Plates with telescopic rails

Telescopic rails

— guides in the form of retractable tray support based on a telescopic mechanism. When removing the baking sheet, the mechanism moves apart, and the stand, rolling on a special roller, “leaves” the oven. The main advantage of the "telescopes" over the classic lattice guides is that you don't need to make much effort to install and remove the baking sheet — the stand moves very easily. On the other hand, such devices are more expensive and more complicated than classic lattice guides, as they get dirty, their efficiency drops noticeably, and severe pollution can completely disable the mechanism. In light of all this, manufacturers most often use the "telescope" not as the main option, but as an addition to the grating described above. If telescopic guides are initially indicated in the characteristics of the stove, this usually means that the oven with a traditional grate is additionally equipped with removable “telescopes” (usually 1 pair, per 1 baking sheet). These advanced rails can be easily set at the desired level and removed for cleaning.
