Brass Lamp Extension Kit

This ten-pack supplies #4-36 coarse-thread brass extensions designed to lengthen lamp turnkeys. Each piece measures three-quarters of an inch and fits compatible lamp hardware. The brass construction resists corrosion in typical indoor environments. Homeowners and maintenance workers can keep a supply on hand for quick repairs.

Material And Thread Performance

Brass threads engage smoothly without binding and tolerate repeated adjustment. The coarse pitch reduces cross-threading risk during installation. No lubrication is required for normal operation. The metal dissipates heat from the lamp base without becoming excessively hot to touch.

Proposition 65 Compliance Note

California Proposition 65 warnings indicate the brass contains chemicals linked to cancer and reproductive harm. The notice does not alter the mechanical function of the extensions. Users should wash hands after handling and keep the parts away from children. No additional safety equipment is bundled with the pack.

Questions about this item

How do I install the #4-36 coarse thread brass extensions onto a lamp socket?

Screw each extension onto the socket by hand until the brass threads engage fully, then tighten gently with pliers; the step most people miss is checking that the 3/4" length clears the harp before final tightening.

Will the brass extensions corrode or need replacement over time?

Brass resists corrosion in normal indoor use, but if the lamp is exposed to moisture or cleaning chemicals the threads can oxidise and may eventually require replacement.

What is the first limit I hit when using these extensions continuously on a high-wattage bulb?

The brass conducts heat, so sustained high temperatures can soften the threads or discolour the finish, making that thermal limit the first constraint under heavy use.
