Plated Nickel lamp harps work well for silver or nickel lamp restoration. Bottom wing pieces of nickel lamp harps slip 1/8IP standard lamp pipe and top pieces have 1/4-27 threads to fit most standard lamp finials. Nickel lamp harps have swivel tops to provide easy leveling of lamp shades. To determine the correct height for your lamp, measure assembled nickel lamp harps from lowest point at the bottom of the wing piece to the base of the finial thread on the top piece. Nickel Plated
