To Our Customers:

We are gratified to hear our users refer to Econo Check as the “Building of Dimensional Checking.” This was our concept when designing this system of comparative measurement.

You will agree that fixtures are difficult to attach to surface plates with “C-clamps”. Our solution was to simply drill and tap a number of holes in our surface plates at covenient locations.

A checking unit was needed that would accommodate more than a single dial indicator. Econo-Check has multipost units and several types of indicator support brackets. You can use as many as six dial indicators on a single Econo-Check unit.

To increase the effectiveness of Econo-Check, basic fixtures, such as parallels, angle plates, platens and positioning fixtures were designed. Each is adjustable. Each is drilled and tapped for easy attachment.

This combination of interrelated “Building Blocks”, coupled with the creative planning of the user, results in quick set-ups for an infinite variety of checking situations.

Remember, Econo-Check fixtures do not have to be amortized on a single job. They are adjustable and can be used time and time again.

We are looking forward to our next opportunity to service you.
