This help you in removing the two supports of the same section thus bending the trays round the overhead beams, alongside other structures which may avoid the normal usage of cable trays. Bending of the trays in some of the data centers may help in networking multiples of free stand server racks, to a single cohesive unit and the use of proper switches is advisable in t
The use of ceiling-mounted designs can also be applied in areas that do not allow the cable trays to easily attach on walls or to the server racks. Proper labelling of the trays should be done before putting the cables in the trays, to avoid confusion.
