Perimeter Technologies, a leading manufacturer of electronic pet fencing, has designed a cost-effective alternative to the once-exclusive Invisible Fence R21 Fence dog fence collar, giving owners of the nation’s largest and best-known professionally installed dog fence brand significant savings on replacement collar receivers.
Don’t be fooled by the low aftermarket price. Perimeter Technologies is a brand you can trust, with products loaded with exclusive features and benefits not found in the original. In fact, Perimeter Technologies' President is the same person who founded the Invisible Fence brand in 1976!
