5/8 Inch Tall Antique Brass Lamp Coupling, 1/4F Tap (21127A)

Hard to find item

I replaced a lamp shade and needed a new coupling (or sleeve). After failing to find any item that worked at four Md-Va-DC hardware/lamp stores, I checked with Antique Lamp Supply and found the the right size coupling in the exact metal and finish that I wanted. And it arrived promptly.
