Harry Soref was a locksmith and inventor. In 1919 he noticed that safe vault doors were made of laminated sections. Mr. Soref decided that if laminated sections provided added security for safe vault doors, then why not use the same laminated design for padlocks? This was a revolutionary idea in an era when many padlocks had simple hollow bodies which could be easily broken. Harry Soref started the Master Lock Company in 1924. His laminated steel padlocks were heavier and stronger than most existing padlocks. Master laminated padlocks became a government favorite and a successful Master Lock company flourished.
A prized possession is a mounted Master laminated padlock. Master Lock had a commercial which was shown for many years during the Super Bowl. The legendary slogan “Tough Under Fire” is appropriate as a Master padlock was shown withstanding a rifle bullet during the commercials. This mounted padlock shows the powerful effect of the rifle shot, but the padlock remains locked.
Master Lock has always been known for their wide range of padlocks but they also have many other products available in the security and safety sector. Locksmith Ledger contacted Master Lock and requested their suggestions for a few other Master Lock products which may be less familiar to locksmiths.
Adjustable Cable Locks

The vinyl coated, braided steel cable offers superior cut and weather resistance. Cables for Model 8413D can be ordered in lengths from 2 feet to 30 feet.
Master Lock 8400 series adjustable cable locks incorporate the Python rekeying system. Python cylinders have 4-disc tumblers and an M1 keyway. A dual sidebar locking system offers maximum pick resistance.

King Pin Locks
A solid, cast aluminum housing weighs only 6.5 lbs for easy handling. An integral Master padlock provides locking security. The 387 series King Pin housing encloses the padlock. There is no exposed shackle to cut. A hardened steel bottom plate on the padlock resists drill attacks or attempts to pull the cylinder from the housing. The bright red housing and attached red flag indicates from a distance that the king pin is in a locked position. It provides optimum security for both the commercial trucking applications and for private RV and fifth wheel trailers. 387 series King Pin locks use a 4-pin M1 keyway and can be ordered to match existing on-site key systems.
