The Brooklyn Convertible Crib Full Size Bed Rail Kit will transform your Brooklyn 4-in-1 Convertible Crib into a low profile platform bed frame, providing the perfect height for safety, plus easier access for toddlers to climb in and out of bed. Brooklyn accessories make assembly easy with their built-in-hardware. No loose screws or bolts mean it was designed and engineered with added safety since the hardware is pre-installed, so you just have to align and tighten! Headboard not included.
