Replacement Prongs 1-Inch Stainless Steel Points

Best for dogs with short hair, these 1-inch surgical-grade stainless steel contact points are designed for Dogtra remote trainers. They offer corrosion resistance and a long life expectancy, helping maintain consistent boundary signals. Suitable for 1900X and 280X models, these prongs are a strong upgrade when the original probes wear down. Choose this if you need replaceable probes that last and resist wear. A potential limitation is fit compatibility strictly limited to listed Dogtra models.
Accessory Kit for PetSafe Fencing Receiver Collars

Best for PetSafe fence systems, this kit provides long and short contact points, ensuring adaptable contact pressure and better skin contact. It helps prevent false alarms caused by poor contact and supports waterproofing with stainless-steel screws. Best for owners who want a complete replacement set in one purchase. Limitations include incompatibility with some non-PetSafe systems, so verify your collar model first.
SportDOG Long Contact Points, 5/8 Inch

Best for dogs with long or thick coats, these 5/8-inch probes extend beyond dense fur to maintain effective stimulation. They are a practical choice when shorter prongs fail to reach the skin. Choose this if your dog’s coat requires longer probes. A potential limitation is that 5/8 inch may still not be long enough for extremely thick coats.
Accessory Kit for PetSafe Fencing Receiver Collars

Best for owners seeking a broad replacement set, this kit includes contact points, protective caps, screws, and washers. It supports both in-ground and wireless PetSafe collars, improving durability and ease of maintenance. Avoid this if you use non-PetSafe models that require different hardware configurations.
PetSafe Accessory Kit for Fencing Collars

Best for broad compatibility with many PetSafe systems, this kit includes replacement short and long contact points, protective level covers, and mounting hardware. Choose this if you own a PetSafe fence and want a single, all-in-one kit. A limitation is that it may not fit some non-PetSafe models without adapters.
Buying Guide: Key Purchase Considerations
What length prongs do you need? Shorter prongs are ideal for dogs with thin or short coats; longer prongs help reach skin in thicker fur. Consider the collar model compatibility first—prongs must fit the specific boundary collar you own. Materials matter: surgical-grade stainless steel offers corrosion resistance and long life, reducing maintenance over time. Waterproofing features and weatherproof caps can prevent button or screw failure in wet conditions.
How to assess fit and safety? Ensure prongs are not overly long for your dog’s size, as overly aggressive contact can irritate skin. Probes should contact the skin consistently without applying excessive pressure. Use replacement kits that include caps and washers to protect electronics and skin contact points from moisture and debris. If your dog has sensitive skin, test carefully and adjust contact pressure as needed.
Which kit saves time and money? Comprehensive kits that include both long and short points, caps, and hardware reduce the need for separate purchases. They also help ensure you have the right components for rapid replacement after wear. If you use multiple fence systems, verify cross-compatibility with your collars to avoid mismatched parts.
