TIA569Pathways&SpacesStandardPullBoxesandSplices

Pull Box Installation Locate pull boxes in easily accessible locations Horizontal cable boxes should be installedLocate pull boxes in easily accessible locations. Horizontal cable boxes should be installed

above suspended ceilings. Should be used when installing a pull string or cable, fishing the

conduits run, and pulling and looping the cable in the next length of conduit.

Pull boxes should be used when:Conduits runs are more than 30m (100)Contain more than two 90 bends.

P ll bo es shall not be sed for splicing cablePull boxes shall not be used for splicing cable.

Splice boxesIntended to be used for splicing in addition to pulling cable. A slip sleeve is a conduit sleeve that is larger than the main conduit, and slipped over an opening in a conduit run after the

cable is in place. A gutter is a square, sheet-metal housing, which is placed over an opening in a conduit. Slip sleeves or gutters cannot be used for splices, but can be used in

place of a pull box, are more economical to install, and will provide more space for pulling.

OtherStandardsandTIA569

Because ANSI/TIA-569-C is now a generic reference for pathways, specific requirements unique to an application will p y p q q ppbe specified in the application standard.

For example, specific pathway and spaces requirements for commercial buildings will be specified in ANSI/TIA-568-C.1.

Specific pathway and spaces requirements for healthcare facilities ill be specified in ANSI/TIA 1179facilities will be specified in ANSI/TIA-1179.
