Shop 66 wiring blocks and accessories for telephone distribution, PBX systems, analog voice wiring and legacy telecommunications cross-connect applications. Wallco offers split 66 blocks, telco-interface blocks, bridging clips, protective covers and related connection hardware.
Compare products by pair capacity, block configuration, telco interface, bridging requirements, mounting style and accessory compatibility.
66 blocks provide accessible termination and cross-connect points for telephone and other low-voltage communications wiring. They remain common in existing PBX systems, analog voice installations and telecommunications environments where service and maintenance require traditional 66-style hardware.
Split-block configurations divide contacts into separate termination fields and can be used for cross-connection, distribution or bridging arrangements. Verify block construction and wiring requirements before replacing an existing 66 block.
Prewired assemblies may transition a 66 termination field to one or more multipair telco connectors. These products can simplify connection to PBX systems and other equipment using 25-pair telecommunications interfaces.
Bridging clips electrically join adjacent contacts on compatible 66 blocks. They are useful for selected distribution and testing arrangements and should be matched to the block design and intended circuit configuration.
Clear or colored covers can protect the termination field while keeping connections accessible for inspection. Use accessories designed for the specific 66 block so mounting and clearance remain correct.
Identify the block style and required pair capacity, then determine whether the installation needs a standard termination block, telco transition, bridging clips or protective cover. For existing systems, compare the original wiring arrangement before changing hardware.
