How to Use a Lampshades Converter & Washer Adapter: Transform Any Shade into a Harp/Finial Style Lamp

 

Have you ever fallen in love with a beautiful lampshade only to realize it doesn’t fit your lamp base? You’re not alone. Lampshade fittings differ between regions and lamp types, and that mismatch can be frustrating.

In North America, most table and floor lamps use the harp and finial system, while many imported or modern shades feature a utility, Euro, or Uno fitting. Luckily, you don’t need to buy a whole new shade. A converter/adapter system with converting washers can easily transform a standard utility fitting into a harp-style shade in minutes.

This simple accessory bridges the gap between different lamp fittings, allowing you to enjoy your favorite lampshade, no matter where it came from.

 

What Is a Lampshade Converter or Adapter?

A printed lampshades converter (also called an adapter ring) is a small yet essential component that modifies the center ring (fitter) of your lampshade frame. It allows a shade made for one style of lamp base to fit another.

For example, a typical converter will transform,

“A standard frame with a utility (E27 or B22) fitting into one that fits a harp and finial system.”

That’s exactly what most homeowners in the Canada and USA need since harp fittings are the dominant system here. The converter acts as a bridge between the lampshade’s washer ring and the lamp’s metal harp.

 

Understanding Lampshades Fittings

Before diving into installation, let’s understand the main types of fittings,

Fitting Type	Where It’s Common	How It Works
Utility / Uno / Euro (E27 or B22)	Europe, Asia, modern fixtures	The shade sits under the bulb socket using a ring that locks between the bulb and socket.
Spider (Washer) + Harp + Finial	North America	The shade rests on a harp frame and is secured with a decorative finial on top.

The converter system lets you use shades across both systems without needing to modify or replace the shade.

 

How the Converter & Washer System Works

A complete converter kit generally includes,

-       1 Metal or plastic adapter ring

-       2 converting washers (top and bottom)

-       Optional finial screw or spacer

 

Step-by-Step Function

1.    The adapter ring reduces the center hole of your lampshade’s frame to match a harp stem.

2.    Washers provide support on both sides of the frame ensuring stability.

3.    The harp rod passes through the center hole and secures the shade between two washers.

4.    Finally, the decorative finial screws onto the harp to lock the shade in place.

Once installed, your shade sits perfectly aligned just like it was designed for a harp system from the start.

 

Step-by-Step: How to Install a Lampshade Converter

Follow these simple instructions to convert your lampshade,

 

1.    Remove the light bulb.

If your lamp has a socket ring, unscrew it to expose the base.

2.    Insert the converter ring.

Fit the adapter into the center of your lampshade’s existing frame (utility fitter). It should sit snugly and level.

3.    Attach the harp frame.

Clip or screw the harp into place on your lamp base. The threaded rod (called a saddle stem) should extend above the socket.

4.    Add the first washer.

Place it over the harp’s threaded rod—this acts as a seat for your shade.

5.    Set the lampshade.

Lower your shade (with the adapter installed) onto the harp stem, resting it on the washer.

6.    Add the second washer.

Position it on top of the adapter ring to lock the frame securely.

7.    Screw on the finial.

Tighten gently by hand. Don’t over-tighten—just enough to keep the shade level and steady.

8.    Reinstall the bulb.

Choose an LED bulb to reduce heat and protect your shade fabric.

That’s it! You’ve successfully converted your lampshade to fit a harp-and-finial system.

 

Why This System Is Perfect for North American Lamps

In North America, the harp/finial design remains a timeless favorite because,

-       It keeps shades stable and centered.

-       The finial adds a decorative accent.

-       It’s compatible with most high-quality table and floor lamps.

So, if you’ve imported a lampshade or bought one online with a Euro fitting, this conversion kit ensures it can fit perfectly on your North American lamp base saving you both time and money.

 

When to Use a Converter System

Use a lampshade converter when,

-       You own a shade with an E27 or B22 utility fitting.

-       Your lamp base has a harp/finial top.

-       You’re upcycling or mixing and matching old and new pieces.

-       You’re a DIY enthusiast or interior designer adjusting shades for custom projects.

Avoid it only if the shade doesn’t balance properly or if the harp rod size is non-standard. Always check that the assembly is stable before turning the lamp on.
