Cable Ladder Systems-Ancillary Items & Covers

Ancillary Items

Bendable connectors

Bendable connectors are supplied in pairs with fasteners, used for fabricating accessories on site to make up bends, reducers and compensate for misalignment of straight lengths. Application: Fabricating accessories on site from cut lengths of cable ladder, e.g. a long articulated bend; correcting minor mis-alignment problems; Reducing width of a run to the next size down when a properly manufactured reducer is not available.

Flexible expansion couplers

Flexible expansion couplers are supplied in pairs with fasteners, used to provide a semi-flexible joint to compensate for relative movement when spanning separate structures or changes in ladder lengths due to temperature variation.

Dropout plate

Dropout plate is supplied with fasteners, used to provide local support for cables as they exit a cable ladder run between rungs.

Rail-to-rail dropout brackets

Rail-to-rail dropout brackets are supplied in pairs with fasteners, used to attach a vertical run of ladder or tray beneath a horizontal main ladder run

Tee brackets

Tee brackets are supplied in pairs with fasteners, used to create a branch of a straight ladder run. Couple with vertical hinged connectors or bendable connectors to offset the branch.

Short reducer brackets

Short reducer brackets are supplied singly with fasteners, used to form a reducer on site, can also be used to convert an equal tee into an unequal tee. For straight reducer, use in pairs. For offset reducer, use singly with straight coupler.

  • Offset reducer: Y = W - K
  • Straight reducer: Y = (W - K)/2
  • W = main ladder mm
  • K = reduced ladder mm
  • Ancillary mounting bracket
  • Ancillary mounting bracket are supplied singly with bracket to ladder fastenings
  • Ancillary mounting plate
  • A n c i l l a r y m o u n t i n g p l a t e s a r e supplied singly with bracket to ladder fasteners. Slots for M6 fasteners are provided for mounting ancillary items.

  • Covers for Medium Duty, Heavy Duty & Extra Heavy Duty

    Covers are supplied with clips and fasteners. Covers for both closed and ventilated installations are common (except when using inside and outside risers) 600 mm wide and above are overlap jointed for rigidity.
