Our polyurethane-coated 1" collar is rugged and waterproof, just like the original collar that came with your dog tracking device. The collar has a nickel plated square buckle and collar keeper and has holes spaced to fit most dogs. Comes with a 3 line brass name plate and rivets. This collar fits T5 and TT15 full size collars. (The beagle size collar is shorter and has only one set of rivets by the buckle to allow more adjustment for a smaller dog)
