The 4.0mm Collar Bundle features the durable Boss Buckle, designed for strength and style. Made from high-quality Zinc, these buckles are available in three finishes: Black, Silver, and Antique Brass.

This bundle includes a variety of 4.0mm collars crafted from materials such as Chrome, Stainless Steel, Black Stainless Steel, and Curogan. These buckles are specifically designed to fit Herm Sprenger collars that have two end links and a center dividing plate. The Boss Buckle replaces the center plate, so it is essential that your collar has opposite-facing links for proper functionality.

Safety

Always remove a prong collar if your dog is unsupervised, tied up, or playing with other dogs. The buckles and collars are not designed to come off on their own, but for any prong collar, (with a buckle or not), please use a safety back-up method in case your collar does come off during use. Katie's Buckles is not responsible for any damage or injuries. The customer assumes all risk and liability.

I suggest contacting an experienced trainer local to you for proper fit and instruction on any type of training collar.

Note: some owners have reported discoloration on white coats from their collars. No full refunds on used items even for this reason.

Katie's Buckles are FANTASTIC!!

These buckles save time, energy, frustration, and I am not constantly bending prongs multiple times a day to put the collar on and off. They allow the collar to fit and sit properly where before I needed more slack to get the leverage to bend prongs to put the collar on. My dog says they are better as well.
