PetSafe Wire & Flag Kit

500 feet of boundary wire, training flags, and splices — for expanding any PetSafe underground fence

The Wire & Flag Kit is the straightforward way to add area to an existing PetSafe underground fence installation. You get 500 feet of boundary wire, training flags, and wire splices in one kit — everything you need to extend the boundary loop without buying components separately. Compatible with all PetSafe in-ground fence transmitters.

If you’re doing a first-time installation rather than expanding an existing system, most PetSafe fence systems already include wire and flags in the box. This kit is intended for expansion or for replacing damaged wire runs.

Have a wire break? Before adding wire, use the Wire Break Locator to pinpoint the break location first. Replacing the entire run when only a small section is damaged wastes wire and time.
