An excellent choice for poultry breeding houses or dog kennels, 24" x 48" White Interlocking Non-Overlapping Dura-Slat Poultry & Kennel Flooring is made of high impact, wear-resistant polypropylene plastic. Its non-porous smooth surface has 1.1” square openings to allow manure and dirt to fall through it - cutting the cleaning time in half compared to traditional wood slat floors. A cleaner floor means less contamination of chicken eggs and healthy dogs too! Rot and corrosion-proof, the solid plastic construction resists microorganism buildup. This durable material easily outlasts wood slats
