Genuine Dogtra titanium contact points — the two prongs that screw into your Dogtra receiver and rest against your dog's skin to deliver the signal. These are male-thread contacts.
At 1" (max) these are the longest points, for very thick or long double coats. Titanium is hypoallergenic (nickel-free and biocompatible — kind to sensitive skin) and highly corrosion-resistant, so they're happy in water; any natural discolouration over time is harmless oxidation.
Sold as a pair. Male contacts fit Dogtra X-Series (640X, 1200X, ARC-X), CUE Series, Pathfinder2, Smart No Bark, GPS Fence and 200iQ receivers. Hand-tighten to fit.
