Use the six-inch Nicolock Colonial Wall System to create elegant walls and structures with a classic appearance that will enhance your outdoor space. These solid landscaping wall blocks feature a double-sided, hard-split rock face texture that mimics the look of quarried stone. In addition to building retaining walls, this system is also perfect for creating functional and decorative features like stairs, landings, fire pits, planters and piers. For added character and depth, pair the six-inch Colonial wall blocks with the three-inch Mini Colonial Wall System. This combination will result in unique, multi-dimensional structures that really stand out.
