CRL Stainless Steel Post Kits for Gates are made from 316 grade stainless, and are offered in either surface mount or core mount types. Both are available in 2-1/2", 3", and 4" (64, 76, and 102 mm) square profiles, made to your custom height specification. The size of the post is dependent upon the overall width and height of the gate being attached to the posts. For Core Mount Post Kits we recommend using Expanding Cement.
