Comstock Buys PTI and Digitech Security Brands From Chamberlain Access Solutions


Lance Comstock, the founder and former owner of PTI Integrated Systems Inc. (PTI), purchased the PTI and Digitech International Inc. brands from Chamberlain Access Solutions Inc. on Oct. 14. The security products will now be sold through Comstock’s new company, PTI Security Systems.  

PTI, a developer and manufacturer of access-control, security and site-management solutions for the self-storage industry, was established by Comstock in 1979 and acquired by The Chamberlain Group Inc. in October 2007. Three months later, Chamberlain acquired Digitech, which has developed and marketed access-control and security systems for the self-storage industry for more than 20 years.

The acquisitions, part of The Chamberlain Group’s growth plans in the integrated access-control industry, lead to the creation of Chamberlain Access Solutions, a developer and manufacturer of integrated access control, site security, and facility management products and services for the self-storage industry worldwide.

The Chamberlain Group is among the world's largest manufacturers of residential and commercial door operators, access-control products and gate operators. It is one of the cornerstone companies of The Duchossois Group Inc., a privately held, family-owned company with holdings in the consumer products, technology and service sectors, valued in excess of $2 billion dollars.
