This Emuca Drawer System is designed for a 900mm-wide kitchen unit. The base features flaps that can be cut to adjust to the inner measurements of the drawer, ranging from 768-836mm in width and 414-482mm in depth. It effectively prevents buckets from moving during drawer operation (buckets not included). Constructed from durable anthracite grey plastic, it allows for combinations of 2 to 4 containers of various sizes.
