Green Technical Services, Inc. is an authorized service provider for cart retention systems (also referred to as cart containment systems or sometimes as electric fences). These are systems designed to prevent shopping cart theft by locking the cart wheels when they reach the boundaries of your defined area, such as your parking lot. We install and repair all components of these systems - electronic, mechanical, or even the signage on the cart or around the premises.

Service is provided by our professional technicians, who arrive on site in a van stocked with our most commonly needed parts. This allows most jobs to be completed on the first visit, assuring minimal down time and maximum customer satisfaction.

We service all top manufacturers, most notably Carttronics and Gatekeeper Systems. Through our experiences on many varied types and models under these manufacturers, our knowledge is at a level where we can competently repair any other manufacturers as well.

The following are just some of the alternatives offered by these manufacturers:
