Phone line surge protection for punchdown blocks

Our Snapit protectors fit on standard 66-type punchdown blocks, and are generally used on the phone company's RJ21X demarcation.

Each Snapit protects one pair of wires (for one phone line), and bridges across the center of a split block.

A grounding bar connects to multiple Snapits on the punchdown block.

Two versions are available: 130 Volt for central office lines, and 30 Volt for use within a phone system, where you have phones in several buildings.
