The Economy 1800×900 lattice is conveniently sized, versatile and ready to install. Constructed with 35mm (wide) x 7.5mm (thick) battens with approximately 75mm diam openings and galvanised hardware. <br Our lattice is ACQ treated, meaning it is arsenic-free and safe to use in veggie patches, and in and around kids and animals. This water-based treatment protects the timber against termites, fungi and rot. <br All our lattice is made from FSC timber which is sourced from sustainable forests only. Feel free to paint or stain your lattice or simply use it as you like.
