Got a wobbly lamp or a chandelier that needs fixing? These ITROLLE lamp pipe nipples are here to help! Each one is a solid zinc alloy adapter that converts internal M10 threads to external M12 threads – super handy if your light fixture doesn’t quite match up. They’re 20mm long (about 0.78 inches) and made from tough iron metal with a galvanized finish to resist rust and corrosion. Super easy to screw in and out – no special tools needed. Great for repairing pendant lights, candelabras, or any light fittings around the house. You get 4 pieces in the pack, so you’ve got spares for future DIY projects or multiple fixtures. Just double-check your thread sizes before ordering – and keep in mind there might be tiny size variations due to manual measuring. A must-have for home improvement, electrical projects, or just keeping your lighting secure!
