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.

Questions about this item

Does the 1/87 scale fifth wheel generate any heat or noise when displayed all day?

The plastic model has no moving parts or electronics, so it produces no heat and makes no sound during continuous display.

What existing HO scale tractor or trailer must I already own to use these 0.375-inch diameter fifth wheels?

Any 1/87 scale tractor unit or trailer designed with a standard king-pin mounting point will accept the three fifth-wheel pieces.

Will the 3-step 3D-printed detail match the finish of older Promotex HO accessories I already have?

The officially licensed parts are moulded to true 1/87 scale, so their surface texture and proportions align with earlier Promotex HO releases.
