The black rubber underlay for the front centre floorboard trim strips is a genuine Royal Alloy spare part for the GP, JPS and TG model ranges. It forms part of the multi-piece floorboard trim assembly and is fitted underneath the corresponding decorative trim strip. The same version is used on both the left and right sides of the vehicle.
As the lower element of the floorboard trim assembly, the rubber underlay forms an intermediate layer between the associated components. If damaged, deformed or missing, it can be replaced separately without having to renew the complete floorboard trim assembly.
The underlay has a narrow, almost straight profile with rounded ends. Several openings are distributed along its entire length. In addition to three rectangular openings, the material features five smaller, approximately round holes.
The different opening shapes and their arrangement are adapted to the construction of the corresponding floorboard trim strip. Near one end, the rubber profile also features a clearly visible stepped section. These design features help ensure correct alignment of the replacement part during installation.
The black rubber material forms a flexible intermediate layer within the floorboard trim system. It can cushion minor movements and direct contact between adjacent components. The rubber underlay is a separate spare part and should not be confused with the visible upper decorative trim strip.
Before installation, the relevant floorboard trim strip should be removed and the underlying contact surface cleaned. It is also advisable to inspect the adjacent trim components and existing fasteners for damage.
The rubber underlay is positioned according to the shape of the floorboard trim strip. The existing openings and stepped profile section help determine the correct orientation. During installation, make sure that the rubber lies evenly against the surface and is not pinched or twisted.
In the Royal Alloy spare parts catalogue, original part number 0312020022-10-001 is listed as the lower rubber strip for the left and right outer positions. A different part number is specified for the inner version. The exact installation position should therefore be checked when ordering a replacement part.
The genuine rubber underlay allows the corresponding floorboard trim assembly to be repaired without replacing unnecessary components. Its predefined contour and hole pattern ensure correct positioning within the multi-piece trim assembly.
