Lamp harps are the mechanism that holds the lamp shade on the lamp. If you are changing a lamp shade, chances are good the
lamp harp will need replacing too. Shades must rest on a lamp to hide the bulb and give you access to the socket switch.
The harp height should be considered when replacing a lamp shade but do not let it keep you from getting the shade you want. Harp range in size from 4 inches to 15 inches and like shoes come in 1/2 sizes.

Harps usually have a metallic finish in brass, nickel, bronze, and antique brass. Most harps are made of steel with a metal finish. Some
boudoir lamp harps are solid cast brass.

For typical lamp harps the harp connects to the harp base. Some older harp bases are narrower and will not seat a new harp. All harps are sold with a matching base, so the old harp base would need to be replaced. Harp bases are mostly standard width and slip a 1/8IP lamp rod. Other options include
wide harp bases, a
center hole that slips 1/4IP lamp rod, and harp bases designed for
plastic sockets with ring.

Harps should be locked in the base and securely seated. The locking couplings are designed to hold the harp to the base even if the lamp is tipped on its side.
