Harps are attached to your wired lampbase in order to hold your lampshade in position. We stock wire harps, which require a threaded nipple, nut and finail to secure your lampshade, and we also have two part bronzed metal harps which have a 6mm spigot at the top, ready to take your choice of finial. If you want to elevate your shade futher, you can add a riser.
