Delta CH 5 Slim (CH5SL) horseshoe nails are high-quality 1.9-inch (approx. 51-52 mm) steel nails, often used for thin-walled hooves due to their slim shaft, which reduces hoof displacement. They feature a City Head, a sharp, exact-bevel point, and a slightly longer shank for superior hold in varied, especially drop-forged, shoes.
