BASIC LAMP ASSEMBLY GUIDE
Follow the illustrations below to see the basic parts and assembly steps required to make a typical lamp. When in doubt seek the help of a qualified professional.

CHOOSING THE CORRECT SIZE LAMP SHADE & HARP (Shade Holder)
Generally, the height of a lamp shade should be the same or slightly shorter than the height of the lamp body. The circumference of the shade bottom should be approximately 2-1/2 times the circumference of the widest part of the lamp body. The shade should be placed so it covers the socket when viewed at eye level. Note: 2-Piece Harps make it easy to switch to larger or smaller Harps (Shade Holders).

SOCKET ASSEMBLY & LAMP WIRING GUIDE
Place steel washer, rubber washer & locknut onto end of threaded rod. Insert threaded rod into your lamp base. Add a rubber washer & locknu5t to top of threaded rod. Tighten against top of your base finger-tight. Slip vase cap, neck, harp base & socket bottom onto threaded rod & tighten finger-tight. Run lamp cord up through threaded pipe as shown in illustration below. Make an electricians' knot to prevent wire from being accidentally pulled loose (see illustration 1 & 2 below right). If necessary, carefully strip 3/4" of insulation from end of lamp cord. If ends are not tinned, twist each section tightly. Wrap the wire with "smooth" insulation clockwise around the brass "hot" terminal screw. Tighten screw. Wrap the wire with "ribbed" insulation clockwise around the silver "neutral" terminal screw. Tighten screw. If using a shell-type socket (below left) press cover securely into socket's base.
