Planet Fitness Ab Coaster CTL - Serial Number Location

The serial number on the AbCoaster® CTL consists of an alphanumeric code that identifies the production batch of that particular unit. It will start with 2 or 3 letters (most frequently ABS or SW) followed by a series of numbers and letters. The sticker with the serial number will be located on the inside edge of the U base frame or under the faceplate on newer models (these can be identified by having metal end caps that have been welded on). Older models will have their sticker on the bottom of the seat mount plate (for models with hard plastic end caps).

When asked for the serial number and you are unable to locate the sticker, please feel free to send a picture of where you believe the serial number should be, and a picture of the entire unit to and we will be happy to assist you in determining the make and model of your unit.
