Riser-rated bulk UTP cables, typically marked CMR, are designed for vertical runs between floors and other pathways that do not serve as air-handling spaces. Plenum-rated bulk UTP cables, marked CMP, are intended for spaces used to circulate environmental air, such as drop ceilings or raised floors, where the application calls for a plenum-rated cable jacket.

Choose Cat 6 bulk UTP cable for standard network installations and expansions that use solid, unshielded four-pair cabling. Choose Cat 6A when you want additional performance headroom for higher-bandwidth applications or future network expansion, and select a riser or plenum jacket based on the cable pathway.

When selecting bulk UTP cables, look for solid bare copper conductors, commonly 23 AWG, with four twisted pairs to support structured network cabling. Choose the cable category, such as Cat 6 or Cat 6A, and select a riser or plenum jacket based on the installation pathway, while considering bulk packaging that supports controlled dispensing during the installation.

Bulk UTP cable in express boxes uses a twist- and tangle-free figure-eight configuration that can support smoother dispensing and easier handling during installations. Wooden spools provide a stable format for pulling longer cable runs, while both packaging options help keep the cable organized on the job site.
