CABLERACK™
CABLERACK™ is used for ladder or basket tray mounting
and securing 19-inch rack equipment for Data centers,
Telecommunication rooms and other locations. The fixed, open
frame rack allows suspending 19-inch rack equipment from Ladder
Rack or Basket Tray. The rack has universal tapped holes per
industry standards to accommodate typical applications. These
open frame racks are ideal for high-density cabling applications
which require above-the-cabinet mounting of equipment, and
provide maximum access to cables and equipment. CABLERACK
is ideal for Data Center applications, expanding equipment to
above-the-cabinet while providing increased equipment and cable
densities.
