these are the metal strips that run between each of the bed boards. They are made from high quality stainless steel, and then polished to a high shine. All of our bed strips are 1 1/2 wide and 18 gauge thick. Brothers strips are pre-punched with square holes, to save you time and effort. It also makes installation a lot easier! All of Brothers bed strips included in these specially priced kits are in complete sets.
