Rated 5 out of 5 by from Good quality, good price, easy to wire These standard T/C connectors are easy to use and are made to last. We use them on gas turbine T/C's

Rated 5 out of 5 by from Solid trouble free connector I love using these connectors over the other ones we have used. The biggest improvement is the clamp that hold onto the cable preventing the cord from being pulled out of the clamp. I make between 50 and 100 5' cords for temperature testing boxes for our small section of my industry every year. I repair the cords I make as well. In the last year, I have only had to replace a handful of plugs that were soooooo abused they broke.

Rated 5 out of 5 by from great jack we have used other k type connectors, but these are the best i have ever seen. i love the way they lock on the cable, plus there are "gromets" to seal connector.

Rated 5 out of 5 by from Perfect. Great quality The fit is perfect. Very solid design and each connection has a tight fit. The controller seems to be more accurate with using these versus twisting the wires together.

do you have a part number for a replacement back plate for the strain relief.

Asked by: spencer
Thanks for your inquiry. The back plate for the strain relief is not sold separately, but as part as an accessory pack (5 in a pack). The part number is OSTW-CC-K-125, and this will contain 5 each of: the colored cap, the back plate, and grommets. The cost of this as of the date of this reply is $17.75/pk. Thank you.
