A package of 12 sets of clip-on spacers for the ends of Sullins edge connectors that properly center the socket on the contact strip of a Circuitron brand Tortoise switch machine. These are the long awaited solution to poorly fitted edge connectors on the popular Tortoise switch machine. These are the same spacers we use with all of our Tortoise adapter products.
Each spacer clips over the end of a connector socket and snaps into place.
Again, our spacer clips come in a handy pack of 12 pair.
