Overview
The Du-Bro 4-40 Rigging Couplers are precision-machined couplers that join two 4-40 threaded pushrods or rigging components into one continuous run. The internal threading provides a strong, slop-free junction, making it easy to extend pushrods or join multi-piece linkage assemblies.
Sold as a 4-pack — enough for typical multi-rod installs.
