The footboard extension brackets are crafted for attaching to headboard-only style bed frames, enabling the addition of a bolt-on footboard or extending the existing one. Compatible with Twin, Full, Queen, and King size frames, these brackets offer adjustable length for a custom fit. Made from superior steel, 20% thicker than standard, they boast a baked finish surface that resists deformation and rust. Installation is straightforward, with seven different sized holes to accommodate various bed frames. If the seven holes do not align, additional holes can be drilled for a perfect match. The brackets fit within a 14-inch bed frame range. Before purchasing, ensure to measure the hole size of your bed frame to match the brackets, as per the size chart provided. The package includes two footboard extension brackets, six bolts, six locking nuts, one wrench, six nut protection caps, and six flat washers, ensuring all necessary components for a secure installation.
