The Fiber-Duct

™

 2x2 and 4x4 Routing Systems are 

comprised of channel, fittings, and brackets designed 

to segregate, route, and protect fiber optic cable 

and copper cabling. It is suited for data center 

applications where cable is routed from distribution 

areas to equipment cabinets or racks. It is used in 

Telco Central Offices to route fiber optic jumper 

cables between fiber distribution frames and 

equipment bays. It can be deployed over the  

racks or in approved under floor applications.  

Fittings maintain a minimum 2

" bend radius to 

protect against signal loss due to excessive cable 

bends. Available system colors are yellow, orange,  

black, and light gray to differentiate various types of 

cabling. A full complement of brackets is available to 

attach system components to support structures 

found in all applications. The Fiber-Duct

™

 2x2 and 

4x4 Routing Systems are part of the Panduit 

complete fiber distribution system, which includes 

the FiberRunner

®

 24x4, 12x4, 6x4, 4x4, and 2x2 

Routing Systems, cable management, and racks.

Large capacity 2"x 2" 

and 4" x 4" sizes

Ideal for routing, segregating, and protecting large amounts of fiber 

cabling; provides a more secure installation for fiber or high performance 

copper cabling

Minimum 2" bend radius  

control fittings

Bend radius control in fittings helps prevent excessive bends in fiber optic 

and high performance copper cabling

Snap-on covers

Covers snap on or off channel and fittings to enclose or gain access to 

system; fully encloses the channel to provide protection per UL 2024A; 

provides quick and easy access for moves, adds, and changes

Mates to Panduit cable

The 2x2 and 4x4 routing systems shall be used to route, segregate, and protect  

fiber optic and communication cabling. The solid wall routing systems should be  

UL Listed as an optical fiber channel for general purpose use. They shall be 

compliant with UL 2024A and NEC articles 770 and 800 when installed per 

instructions. The slotted wall channel and cover shall be UL Recognized. A  

full complement of fittings with a 2" minimum bend radius, snap-on covers, and 

mounting brackets shall be available. Channel and fittings shall be manufactured 

from impact-resistant and flame retardant (V-0) materials. Channel shall have  

non-slip snap-on covers that can be easily removed to allow access for moves, 

adds, and changes. Channel and fittings finish shall be pure color, resist

scratches, dents, and not peel or corrode. Available system colors shall be  

yellow, orange, black, and light gray. A full complement of brackets shall be 

available for attaching system components to ladder rack, threaded rod,

auxiliary framing, equipment racks, and raise floor pedestals.
