Screw-LockTM Pushrod Connectors

Screw-Lock Pushrod Connectors lineart

Round pushrod connectors are difficult to grip-and screwdriver blades often slip right off those slotted-head screws. Our designers solve both problems with squared connectors that can easily be gripped with a pliers or wrench, and socket-style screws.
