Cable trays (cable bridges) are used to protect cables from damage. They are usually made of a durable material such as rubber or plastic and are designed to provide protection for cables that may be subject to damage. Track rails or cable protectors can be single-channel or multi-channel, depending on whether it is necessary to protect only 1 cable or several cable bundles. The crossing rail or the transition rail for the cable is an important safety element that can help prevent accidents and reduce the risk of cable damage. They are especially important in high-traffic areas where there is a risk of tripping or other cable damage.
