It is identical to the 80840 Motorized Tethered Mouse Activity Wheel without the motor assembly.
If you are starting from scratch and need a voluntary running wheel for a tethered animal, please refer to the Model 80840WB Scurry Tethered Mouse Wheel.
Use this activity wheel only if you have an existing AWM based activity monitoring package. Contact a Lafayette Instrument Co. representative to see if this wheel is available, to discuss your options and to see if this is the best wheel to meet your needs.
