AR-D/AW-D Series Knob Cover

The AR_P-580AS knob cover mounts directly onto the adjustment knob of AR-D series regulators and AW-D series filter regulators, preventing accidental operation in applications where inadvertent pressure changes could affect system performance or safety. The cover accepts a standard padlock (customer-supplied) for added security, and can be mounted facing any direction relative to the knob for maximum installation flexibility.
