“When You Absolutely, Positively Want to Lock A Door – Use Positive Lock!”


Established: February 1989

Inventor: Ralph Beals

Sales & Marketing: Phillip Murders

In February of 1989, Ralph Beals manufactured the first “TH” series Positive Lock, which is still in production today.  The lock was used to replace drop in lock bars, which added to a doors security but were easily misplaced. Positive Lock, which locks both sides of the door simultaneously, is securely mounted to the door at all times. 

As Safety and Building Codes evolved so did Positive Lock. When Panic Hardware became a requirement, Positive Lock manufactured the THP.  The THPA Series then followed suit when door alarms became necessary.  The THPA gained notoriety as “UL listed” Panic Hardware, but also as a high security lock.  Due to the increased security, retailers nationwide began placing Positive Lock’s THPA Panic Hardware on their doors to prevent break-ins, and to alert management of an unauthorized open door. Positive Lock now has a delayed egress system which gives a store additional time to stop a thief.
