No knockout tab = no chain — this plug terminates the line, no downstream stringer attaches. Slide-on insulation-displacement contact teeth bite through the SPT-2 jacket when the cover snaps. Use this when your run ends at the last bulb (no chain to next stringer); use the knockout-tab variant when chaining.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003c!-- Section 2.5 (preserved): Why SPT-2 Female Plug (no knockout) — handcrafted prose preserved from existing PDP --\u003e\n\n\u003ch2\u003eWhy the SPT-2 Female Plug (no knockout) earns its place on the contractor truck\u003c\/h2\u003e\n\n\u003cp\u003eThe SPT-2 Female Gilbert Zip Plug is the contractor-grade end plug for building custom Christmas light strings and extension cords on SPT-2 zip cord wire. \u003cstrong\u003eThis version comes without a knockout tab\u003c\/strong\u003e — for installs where you don't need the optional pass-through and want the cleaner, lower-profile finish.
