These rollers are specifically for the Truma Tandem Twin Mover - they will not fit any other model!!

The Truma TwinTandem has extra long motors as they have a solenoid on the end, so unless you have this design of motor you do not have a twin tandem and therefor these rollers will not fit.

Please study photos for measurements 

These are in used condition, i have added 2 photos of each roller showing the missing grit. They are still in very usable condition, and will come with new outer bearings.

If you are unsure if these are the correct rollers for your mover please ask before ordering.
