This is the white plastic moving block (about 3” X 4”) that the chair mounts to on a Limoss motor system ;as the block moves up and down the stationary motor shaft, the chair goes up and down.  PLEASE NOTE: Each Limoss motor will have a six digit part number; please match the number on the motor you have with the numbers listed by the pictures above, and order the one that matches the number on your motor.

It is very important that you check the number on your motor before you order a moving block, because if you order the wrong one and try to install it on your motor, we can’t take it back.  Installation instructions are listed on Limoss Troubleshooting Guide.
