AttachSI! is the Creative-Cables accessory that allows the SI! lamp holder to be attached to any non-ferrous surface. All you need is a screw and a dowel to attach it to any surface. Whether stone wall or plasterboard partition, solid wood headboard or chipboard bookcase, simply attach the washer and you're done. This washer has a countersunk hole to go flush and not let the screw protrude: the attachment for the SI! lamp is absolutely stable and secure.
