  • Scully Signal Company now offers the Scul-Lock™ Cap for tight fill connection. This tamper-proof locking cap protects oil tanks by preventing theft and contamination. Unlike other systems, the Scul-Lock™ is constructed of heavy duty cast metal with a spring mechanism to ensure longevity and prevent bypassing. The new locking system includes a hand-held key with a rare earth magnet to allow removal of the cap for deliveries. Learn more at
