SD Locking Device

Avoid inadvertent handwheel rotation

DYNATORQUE accessories during manufacturing.


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 handwheels. Pad locks are not included.


Locking devices are fabricated from carbon steel unless otherwise indicated. Cross bolts, washers, and lock nuts are also carbon steel. Stainless steel construction also is available at extra cost.
