Overview
The Beck 20-1740-08 linkage kit is a pipe-style actuator linkage solution engineered for reliable mechanical connections in industrial control applications. This kit features a 1.5″ (38 mm) size with approximately 30 1/2″ (775 mm) length, designed for linkage adjustments ranging from 34 1/2″ to 72″ (876–1,829 mm). Beck linkage kits help eliminate slop in linkage connections, and when properly sized and implemented, help ensure successful, long-lasting installations.
