Marshall Best Security Representative in Wisconsin, Minnesota, and Northern Illinois

We are a full service access control company.  We provide, install, and maintain lock and door hardware, masterkeying systems, electronic card access systems, and IP cameras.

We provide our customers with a full line of access control solutions.

Gappa Security Solutions is a Wisconsin-based Company that combines consistent service with quality products. We are the Marshall Best Security [MBS] Representative in Wisconsin, Minnesota, Iowa, and Northern Illinois.

Gappa Security Solutions offers products that will work within most current Best Access removable core systems. This means you will be able to continue to use your existing master-key structure. 

Also, you will find that our products are quite similar to the hardware you already use: For instance, we offer lever handle locksets, padlocks, cabinet locks, cores, keys, and more. You can check out the product line by going to our Products Page.

We have sales representatives and service technicians who travel throughout the state. We welcome a chance to get together with you and tell you more about how we can meet your security needs.
