Spider-Fitter Lamp Shades

What is a Spider Fitter Lamp Shade?

Spider fitter lamp shades are a type of lamp shade that attaches to a lamp base using a spider fitter. A spider fitter is a metal ring with three or more arms that extend upwards and inwards towards the center of the lamp shade. The arms join at a ring with a hole in the center, which rests on top of a harp fitter attached to the base of the lamp. The spider harp fitter is a wire structure that rises up from below the light bulb socket, up around the bulb, and joins at the top, supporting a screw thread.

The screw thread pushes through the spider fitter's central ring and protrudes through the other side. A lamp shade finial is then screwed on top to secure the lamp shade to the lamp. 

Spider-fitter lamp shades are a popular choice for a variety of reasons, including their versatility, stability, and compatibility with various lamp bases. They are also available in a wide variety of styles, materials, and designs to suit any taste or décor. This includes a wide array of shades of light, from warm and cozy tones to cool and vibrant hues.

Components of a Lamp Shade Spider Fitter

Spider fitter

The spider-fitter is the metal ring at the top of a lamp shade spider fitter. It typically has three or four "arms" that extend upward and inward towards the center of the lamp shade. The arms join at a central ring with a hole in the center, which rests on top of a harp fitter attached to the base of the lamp. 

The number of arms on a spider fitter can vary, but three and four are the most common. Three-arm spider fitters are more traditional, while four-arm spider fitters are more modern. Some spider fitters also have notches in the arms, which are designed to rest on top of a glass reflector bowl. 

Harp fitter

The harp fitter is a wire structure that is attached to the base of the lamp. It rises up from below the light bulb socket, up around the bulb, and joins at the top, supporting a screw thread. The screw thread on the harp fitter fits through the hole in the center of the spider fitter's central ring. 

Lamp shade finial

The lamp shade finial is a decorative knob that is screwed onto the top of the harp fitter to secure the lamp shade in place. Lamp shade finials come in a variety of styles and materials to match the décor of your home. 

Optional: glass reflector bowl

Some spider fitter shades are designed to be used with a glass reflector bowl. The reflector bowl is a curved piece of glass that sits on top of the lamp harp, below the spider fitter. It helps to direct the light downward, preventing glare and creating a more focused light source. 

Spider-fitter lamp shades are a versatile and stylish option for any lamp. They are available in a wide variety of styles, materials, and colors to suit any taste or décor. They are also relatively easy to install and remove, making them a great choice for renters or people who like to change their décor often.

How to Attach a Spider Fitter Lamp Shade

1. Gather your materials. You will need the following:
   Lamp shade with a spider fitter
   Lamp base with a harp fitter
   Lamp shade finial
   Light bulb
2. Unscrew the harp fitter from the lamp base. A screw thread holds the harp fitter in place, which is typically at the top of the lamp base.
3. Place the spider fitter ring on top of the harp fitter. The spider fitter ring should rest on the top of the harp fitter, and the arms of the spider fitter should extend outwards.
4. Screw the harp fitter back onto the lamp base. Make sure that the harp fitter is screwed in tightly so that the spider fitter is secure.
5. Screw the lamp shade finial onto the spider fitter ring. The lamp shade finial should screw onto the center ring of the spider fitter.
6. Insert the light bulb into the lamp socket. Make sure that the light bulb is screwed in tightly.
7. Turn on the lamp. Your spider fitter shade should now be attached securely and stably.

Tips for a secure and stable fit:

• Make sure that the harp fitter is the correct size for the spider fitter ring. The harp fitter should be snug but not too tight.
• Make sure that the spider fitter ring is level. If the spider fitter ring is not level, the lamp shade will not be level.
• Make sure that the lamp shade finial is screwed on tightly. If the lamp shade finial is not screwed on tightly, the lamp shade may come loose.
  
• Use a light bulb that is the correct wattage for the lamp shade. If you use a light bulb that is too high in wattage, the lamp shade may overheat and become damaged.

Measuring for a Spider Fitter Lamp Shade

Getting the right size lamp shade can make all the difference in the look and feel of your room. With spider fitter shades, accurate measurements are crucial for a proper fit and to ensure your shade sits securely on your lamp base. Here's how to measure for a spider-fitter lamp shade:

Why Accurate Measurements Matter

• Stability: A shade that's too large or small can be unstable and prone to wobbling or even falling off.
• Aesthetics: The right size shade will complement your lamp base and enhance the overall aesthetic of your space.
• Functionality: A properly sized shade will provide optimal light diffusion and prevent glare.

Measuring Guide

To determine the correct size for your spider fitter lamp shade, you'll need to take two key measurements:

1. Spider Fitter Diameter:

• This is the diameter of the central ring on the spider fitter.
• Carefully measure across the ring, making sure to include the full width.
• Common spider fitter diameters include 1/2 inch, 5/8 inch, and 3/4 inch.

2. Shade Dimensions:

• Slant Height: Measure the vertical distance from the top to the bottom of the shade.
• Bottom Diameter: Measure the width across the bottom opening of the shade.
• Top Diameter: Measure the width across the top opening of the shade.

Tips for measuring

• Use a flexible measuring tape for accurate measurements, especially for curved surfaces.
• If you're replacing an existing shade, measure the old shade to get an idea of the size you need.
• Consider the size and style of your lamp base when choosing a shade. A larger base will generally require a larger shade.
• Don't hesitate to consult with a lighting specialist if you're unsure about which size to choose.

By following these simple measuring tips, you can ensure that you select the perfect spider fitter lamp shade for your lamp and your space.
