Located in Terryville, Connecticut, the museum is directly across from the original site of the Eagle Lock Company, founded in 1854.

Major collections are displayed by company or theme.

The Corbin-Russwin Room contains a large display of ornate hardware.

One of the animated displays shows how a pin tumbler lock works.

One of the attractions here is the original patent model of the Mortise Cylinder Pin Tumbler Lock designed by Linus Yale Jr., in 1865.
