Chamberlain

Chamberlain Group (CGI), the corporate parent company to LiftMaster, Chamberlain, Merlin, and Grifco, designs and engineers residential garage door openers, commercial door operators, and gate entry systems.

CGI is also the parent company to Controlled Products Systems Group, the largest wholesale distributor of perimeter access control equipment in the United States.

Chamberlain Group has several corporate brands:

• Chamberlain – the company’s do-it-yourself line of garage door openers.
• LiftMaster – the company’s line of garage door openers for professional installers.
• Raynor – the company’s line of garage door openers for professional installers. This line of professional installers is slightly less common than LiftMaster.
• Craftsman – re-branded Chamberlain models sold at Sears. Those products have a “139” model prefix to denote that the Chamberlain Group made them for Sears.
• Clicker – a line of universal garage door remotes.

Chamberlain, LiftMaster, and Craftsman have interchangeable parts, primarily the gear and circuit boards. The greatest difference between the brands is that Chamberlain and Craftsman operate on a split-rail system, while LiftMaster consists of one single solid piece of rail. [Source: Wikipedia]

Additionally, Chamberlain manufactures myQ, a smart home automation system that allows users to control and monitor their garage doors remotely through a smartphone app.
