Outdoor extension cord connections for my palm tree lights. Allowed me to shorten the cords safely

cheaply made, good thing It came with two in a package. plastic is brittle around the sealing nut, but It did work for my application for my water fountain in my pond. Connector is underwater does not trip the gfci anymore

Excelente, cumple su Función.

They work very well

Our old fountain pump burned out. Unfortunately the fountain installer didn't use a conduit for the pump wire. We had to cut the plug off leaving about a foot of wire then reattach the wires using the connectors bought from Amazon. Worked perfectly and very easy to install with no prior electrical knowledge. Our fountain pump had 3 different colored wires. Green (ground) White (neutral) and Black for (live). Just needed to make sure you inserted wires correctly into connector.

These are labeled as M20 and claimed to fit cables that are 0.4 inches in diameter (title) or 10 mm in the specifications. I tried to use them with a 3 wire cable that is just under 10 mm OD but the supplied rubber rings are around 7 mm inside diameter. The product description clearly indicated "with two sizes of rubber ring" but there was only the small ring included. I really needed the product now, so I cut extra insulation jacket off and used the connecters to join the 3 conductors but now it is neither dust proof or water proof. These are probably actually M16 units that were mislabeled. I used it with 14 awg wires and it looks like it would handle a 10 awg wire with no issues.

seals great, I used it to fix a outside cord works good and keeps the water out
