Product Identity

Hubbell Premise Wiring 66 M block provides 25 pairs across 50 clips in a 10-inch depth. It carries CSA and cUL listings plus TIA-568-C.2 compliance for structured cabling installations. The split 66 format suits cross-connect and distribution frames in commercial environments.

Suitability

Installers terminating voice or data pairs on a standard 66 split block will find the 50-clip count matches common patching needs. Builders requiring attached mounting legs or a different pair count must select another model because this unit ships without legs and fixes the capacity at 25 pairs.

Deciding Specification

The block depth measures 10 inches, which determines whether it fits the available rack or cabinet space. Confirm the clearance before ordering because no alternative depth is offered for this part number.
