The SBX series of “ScaleBox” couplers are for full coupler box replacement scenarios.

 

These couplers are supplied with a replacement coupler box that is narrow in profile and a “hat” that configures the box to fit a standard MTL box mounting profile.

​

They are an easy replacement in existing body mount configurations where the box is a completely separate part or for conversion of truck mounted rolling stock to body mount.

​

SBX couplers come with trainline air hoses to even further improve the realism of your converted models.

​

If you are looking to convert models with factory integrated boxes, or most locomotives, the URS series of couplers is likely a better fit. ​
