This solid masonry unit stacks without adhesive or mortar, making it practical for straight or curved wall configurations.

Before beginning, prepare a compacted gravel base to ensure proper drainage and level footing for the first course. Do not exceed the manufacturer-recommended maximum wall height of 2 feet without consulting a structural engineer or using an engineered retaining wall system. Local building codes may require permits for retaining walls above a specified height, so verify requirements before construction.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3276 pounds (pallet)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 126 units per pallet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Wall Height\u003c\/strong\u003e: 2 feet (mortar-free stacked application)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Type\u003c\/strong\u003e: Mortar-free dry-stack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OLDCASTLE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 162004551\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHRISTYS","offers":[{"title":"Default Title","offer_id":51524595089714,"sku":"162004551","price":618.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/15337d29dfa487c64624f90f564e6992.jpg?v=1785452675","url":"https:\/\/voomisupply.com\/products\/oldcastle-162004551-castlewall-retaining-wall-block-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
