OUTDECO'S 6 ft. Horizontal Slat Fence Kit provides strength and durability by using powder coated galvanized steel. The 6 ft. Slat Fence Kit is designed for installing hardwood or synthetic wood slats. The kits are predrilled and ready to be installed onto the OUTDECO post. Purchase the number of posts required for your project, lumber of your preference and number of kits. Each 6 ft. kit attaches one section between two posts. The kit rails are adjustable when installed to accommodate 5/8 in., 3/4 in. and 1 in. thicknesses of lumber. Consult a lumber expert for the best lumber and treatments. The kit also provides 24 - 1/2 in. spacers to allow for consistent spacing between 6 in. horizontal slats. If more spacing is desired the slat spacers will conveniently stack within the slat track. Additional spacers are available separately for more customized results. Please see our install instructions to review the many options of installation.
