CADDY® CAT-CM Cable Support System

Beginning with the J-Hook, ERICO has continued to innovate and develop the complete line of CADDY CABLECAT products to support today's high-performance cable. The CADDY CAT-CM provides a cable tray alternative utilizing rod and strut components together with specifically developed steel brackets.


  • Specially designed U-Hooks and double J-Hooks have large-diameter, rounded support surfaces/edges to avoid overbending and kinking of cables
  • U-Hooks available in a range of sizes for different cable capacity needs
  • Three installation options that can easily be combined resulting in installation flexibility to meet every need
    • Rod-mounted option
    • Cantilever-mounted option
    • Strut-mounted option

The Rod-Mounted option allows for field assembly of the hooks onto All-Thread Rod. Benefits include:

  • Customized intervals between hooks to comply with ISO/IEC 18010
  • Easy level changes - under or over ductwork, piping, etc. - no level change fittings necessary
  • Direct attachment to the ceiling or building structure with threaded rod and CADDY fasteners

The Cantilever-Mounted option consists of U-Hooks mounted with brackets to walls and columns. This option allows for:

  • Cable runs along walls
  • Specification of individual hook spacing as needed
  • Mounting of cable within existing column grid

The Strut-Mounted option is accomplished by assembling the hooks to strut for a cost-effective alternative to center rail cable tray and wire basket systems. This option:

  • Utilizes standard strut which is readily available and provides strength
  • Has sheet-metal U-Hooks (rungs) with specially designed quick-attach nut fasteners for virtually any half-slot strut
  • Allows for customized support spacing
  • Has fittings for horizontal and vertical change of direction - simplifying angle and level changes
  • Offers optional rollers and retainers on the U-Hooks to retain cables and support cable pulls
  • Has protective tubes for the threaded rod to eliminate scraping and cutting of cable sheath during pulling
  • Allows U-Hooks to be mounted on a base (for raised floor applications), thus allowing for a large amount of cables to be organized and neatly routed
  • Provides separate compartments for power and low-voltage cables when using the power divider bracket
  • Extends the width of the tray to a maximum of 600 mm (24") with two separate compartments that may be used for power and low-voltage cables when using the cross support kit


  • Horizontal and vertical runs
  • Variable cable support spacing
  • Support from the ceiling, beam or strut and mounting on the floor
