Journeyman-Pro 515PC Plug & Connector Set 15 Amp 120-125 Volt, NEMA 5-15P + 5-15C, 2Pole 3Wire, Straight Blade, Male & Female Replacement Cord End, Commercial Grade PVC Black (1)

If you need to make a high quality extension cord up to 12/3, this is the plug and receptacle to use. Excellent instructions, easy to attach to your extension cord, durable exterior unlikely to break. If your going to use it outside where it might be exposed to rain, you could inject some silicon in at the top of the device just to be extra safe.. Again this is a well made superior product. Don't waste your time at the big box store, this is it.

Super ok

This product was the second type of plug that I purchased to fix the extension cord I broke. It is so easy to use that I was able to fix my extension cord in about five minutes. Really, that easy. I was unable to use the first product I purchased because it required hand and finger strength that I just don't have. This item is just very, very easy to manipulate and work with. Thank you so much for making this fine product.

These are the best replacement cord ends I’ve used, very quick and easy to swap out and seem to be very durable.

Very easy to assemble and they appear to be quality, although I am giving it a 4 star review as one screw in the male end that would not tighten. Will be ordering a replacement for that end and hopefully this problem isn't common with this manufacturers product.
