Product Research


Overview: The PetSafe RFA-1 is a 500-foot spool of 20-gauge wire for use with an In-Ground Fencing system. This spool has enough wire to cover a 1/3-acre yard. The solid-core, burial-grade wire can be used with the following PetSafe In-ground Fence systems: YardMax, Stay+Play, Free to Roam, and Stubborn Dog.

Wire Length Reference Guide: Here is a guide to how much wire you will need based on the size of the area:

Area Size Length of Wire
1/4 acre 415 feet

Splicing: When splicing together multiple lengths of in-ground boundary wire, the wire splices must be kept waterproof. Optional PetSafe Gel-filled Splice Capsules and wire nuts (RFA-366, available from manufacturer) are recommended.
