Easily Expand Your Existing In-Ground Fence System
PetSafeĀ® Extra Boundary Wire makes it simple to enlarge and customize your existing in-ground pet fence system.
Each spool includes 500 feet of 20-gauge, solid-core copper wire rated for direct burial, allowing you to extend your fence coverage by up to an additional 1/3 acre, depending on your layout and installation design.
Whether you’re expanding into a larger yard, creating custom boundaries, or redesigning your current setup, this durable wire provides the flexibility needed to build a containment system that fits your property.
