With the MACS interchangeable system, you are no longer restricted by the footprints of traditional vent rack designs. There are a lot of possibilities to achieve room density with the wide variety of frames.
MACS gives you opportunities to expand, reduce and move cage stacks from one frame design to another if need be. Feel free to mix and match frames to maximize room density. All the frames in the MACS system are designed to hold the Universal Cage Stack.
And with the flexibility of framing, Alternative Design can help you configure the frames necessary to
maximize your space, density and budget parameters.
On several frames, you can even change from mice cage stacks to rat cage stacks and back to mice again without having to buy a whole new system.
MACS provides versatility you probably didn’t think possible.
Here are the standard frames within the MACS system.
