DT, SRD, and BG Locking Devices
Avoid inadvertent handwheel rotation
Features
Cameron field-mountable locking devices were designed for those critical service applications where avoiding inadvertent handwheel rotation is required. These devices are available for use on all our quarter-turn and multiturn operators when used with our handwheels. Padlocks are not included.
Materials
Locking devices are fabricated from carbon steel unless otherwise indicated. Cross bolts, washers, and lock nuts are also carbon steel. Stainless steel construction is also available.
