Perfect replacement strap for most e-collars, or tracking collars using a 1 strap. Convenient D ring at the buckle. Heavy polyurethane coated nylon is rugged and waterproof, while remaining flexible enough to fit your e-collar or GPS collar. And the strap keeps its flexibility - even in cold weather. Reflective strip runs the entire length of the collar and reflects available light to increase visibility and safety for your dog in low-light conditions. 25 sizing holes are spaced tightly to allow for a perfect fit. Strap width is 1 inch and the length measures approximately 25.25 inches from one end of the nylon to the other (not including buckle). The unique strap material may be cut to your desired length - no need to worry about the collar unraveling or being damaged. Both ends and all holes are heat-sealed for a long-lasting, finished look. 3 smooth, flat rivets add strength and durability, but don't snag. Upgraded nickel-plated hardware is extremely durable and the curved buckle contours your dog's neck and body for comfort. Strap is maintenance free, easy to clean (just wipe with a damp cloth), resists mildew, bacteria, and rotting, and is odor resistant. Available in 8 vibrant colors - choose Black, Red, Blue, Pink, Orange, Neon Yellow, Neon Green, or Purple Proudly made in the USA.
