CableRail Nylon Insert Locknuts are an option when securing a Threaded Terminal to a post. Typically the locknut is used with a retaining washer, then covered with your choice of end cap. Its built-in nylon component prevents the nut from becoming loose. Sold individually.

Don't forget to order a Release Tool
Your installation could be delayed if you are unable to disconnect a cable from a Quick-Connect® fitting! We strongly recommend adding a Release Tool to every Feeney CableRail order!
