A Slotted Washer attachment is the same attachment as our regular washer attachment. The Slotted Washer, though, has a cut-out slot which slips over the electrical cord of your lamp. This is common for pendant lighting suspended from a ceiling electrical cable. The inner span of the Slotted Washer measures 1/2".
