Use gray filler inserts & blank straps to easily change wall switch plate openings to the type you need - from Decora and toggle to blank or cable. Conveniently mix and match on aluminum, stainless steel, or grey light switch covers to create hard-to-find configurations. These dummy fillers allow for a quick solution when upgrading your lighting without the need to change all of your switch plates to match a new device size or shape. Be sure to consider grey phone and cable inserts, too, when updating communication jacks, too.
