Before you start: Mount the bracket. Place the outer edge of the bracket cover over the outer edge of the bracket. Push down from the back to the front to snap the bracket cover in place. - Outside extension (A) secures the bracket cover to not tilt when assembled in the system. - Inside extension (B) secures the positioning depth wise during assembly. - Elfa logo (C) will be positioned in the back end of the bracket cover. Alternative 1: When a bracket cover is used in an ordinary end position The outside extension goes into the hang standard and fills up the empty space, and thereby secures the bracket and the bracket cover from tilting. Alternative 2: Used in a position when sharing slot with single slot-products In this case, there is no space left for the outside extension (as it is replaced with a single-slot product). The extension piece needs to be removed. Do so by breaking it off by the break line. The inside extension (B) will help with positioning during assembly. The inside extension goes into the hang standard during assembly and "hits" the hang standard surface. By that, the bracket cover will be in correct position depth wise so the front end will line up with shelves, trims etc.
