Promotex Fifth Wheel Sets 3 Sets 1/87 HO Plastic Model

Scale model accessory for collectors

This Promotex set supplies three 1/87 scale fifth-wheel assemblies cast in plastic. Each piece measures approximately .375 inches across and arrives in the manufacturer's original unopened packaging. The parts target adult hobbyists who detail HO-scale tractor units or dioramas.

Produced through a three-step 3D printing process

The components are built layer by layer to capture fine surface texture that moulded parts often miss. Because the geometry is printed rather than injected, the coupling jaws and mounting plates hold sharp edges after light cleanup. Collectors can prime and paint the pieces straight from the box.

Lightweight plastic keeps handling simple

The small diameter and low mass mean the assemblies add negligible weight to a finished model. No moving mechanisms are present, so there is no friction noise or wear during display. Power draw and thermal output are not applicable to this static accessory.
