Knaack Manufacturing has recently introduced its Watchman IV lock systems on the company's current Storagemaster and Jobmaster storage chests, cabinets and rolling workbenches. The system requires only 1 padlock for 2-point, dead-bolt latching. According to Knaack, the security of the WATCHMAN IV system is unmatched in the industry. The dual dead-bolt lock system features a 1/2" steel rod with 7-guage steel tangs on each end of the chest cover with latching on the chest ends to prevent thieves from prying up a corner of the toolbox.
