The PetSafe Boundary Kit PRFA-500 allows you to increase the containment area of your PetSafe Containment System.  Most containment systems come standard with 500 ft. of 20 gauge wire that allow you to "fence in" up to 1/3 acre.  This kit comes complete with waterproof wire splicers so that you can increase your containment area by another 1/3 acre.  You may purchase several kits for larger boundaries up to the maximum your containment system is design for.  50 flags are also included so that you can visibly mark off the extended containment area during the training process so you dog can become familiar with the increases roaming area.
