Scale Size

Our N-Possible couplers are scale-sized N scale couplers.

That means no more "boxing gloves" overpowering your finely detailed models.

Reliable Operation

Good looks mean nothing if the couplers don't do their job of reliably coupling cars.
Our N-Possible couplers out-perform other knuckle style couplers by every metric.

Easy Installation

You can't take advantage of the N-Possible coupler if they're not easy to use.
A range of shank lengths and mounting options makes adopting the N-Possible easy.

 
 

N-Possible coupler features realized by the Patent Pending N-Possible spring mechanism:

Precise Scale Design: Enhance authenticity with a meticulously detailed prototypical appearance. Compatible with other scale designs but not conventional couplers.

Ultra-Low Force Automatic Coupling: Experience reliable scale-speed switching with minimal coupling force and easy pick uncoupling.

Easy Installation: The retained spring design simplifies installation into car integrated boxes.

Slip-Resistant Performance: Stays connected on uneven trackwork, maintaining reliability.

Reliable Alignment: Dependable reverse movements and DPU/helper operation.

Versatile Shank Lengths: Three shank lengths for prototypically accurate coupler configurations.

Various Versions Available: Choose spring-mounted versions or kits.

No Slinky Effect: Eliminates the “slinky” effect for a realistic look

 

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.
