 Magnetic Ways: SGLTM-80  A 
Note: 1. Two Magnetic Way tracks are used together as a set. For safety, when they are shipped, the two tracks are
secured to a mounting spacer made from aluminum.
2. More than one Magnetic Way can be connected.
3. Dimensions with asterisks are the distances between the Magnetic Way tracks. Install the tracks according to the
specified dimensions. Observe the dimensions given in Mounting Section Details after installation. Dimensions
when the Magnetic Way is shipped from the factory are indicated by .
4. Use socket head screws of strength class 10.9 or higher for the Magnetic Way mounting screws. (Do not use
stainless steel screws.)
