2PCS DB9 Solderfree Serial to 9 pin Terminal Thin Female Adapter | Solderless, D-SUB Port, Metal Shell Connector, Breakout Board, with Case Long Bolts Tail Pipe, 2PCS Female

Better than I expected. Came in a very nice packaging

Besides being expensive, this connector has many flaws. First, the screws provided do not fit so you cannot clamp the metal backshells over the connector. Next, the metal shell is way to bulky and heavy. It is completely unnecessary to use that much metal. Then, the grommets to hold the cable are plastic, not rubber. So unless you have the right cable diameter, it does not grip and provide strain relief, despite the four sets of cable clamps. With four different options, you might get it right. Last, the threaded rod is threaded too long and can easily short on a wire if you don't strip them perfectly. I am going to look to another source.

Quality control is terrible. One board the connector was extremely crooked. Could not get the screws to line up with the male end because of it. And on one of the cases the screw hole to hold the connector together was not even drilled. Decent product if you plan on only making one good connector while still having to pay for 2.

Not as simplistic as the snap over type you can get, but more durable.
