# 2363 Dunbier H3702RH Mackay Plastic Guard Carrier 14" Tandem RH | Marine Trailer Part

🔧 Product Description

  

Dunbier 14" Plastic-Guard Carrier - Tandem Slipper-Spring RH - Part Number: 2363

  

A formed galvanised steel carrier and step/support assembly for a 14" Dunbier plastic mudguard on the right-hand side of a tandem slipper-spring trailer. The carrier supports the moulded guard, provides its mounting points and helps transfer incidental step loads into the trailer undercarriage rather than through the plastic guard alone.

🚤 Trailer Compatibility & Application

  

• Suitable for Dunbier trailers using the matching 14" plastic guard and tandem slipper-spring carrier arrangement

• The right- and left-hand carriers are not interchangeable

• Confirm spring layout, axle count, overlay style and undercarriage mounting points before ordering

• Wheel and tyre clearance must be checked through the full suspension travel

  

🔌 Function

  

Supports the plastic mudguard and provides a rigid mounting structure around the wheel or tandem wheel group.

  

Common signs of wear or failure:

  

• Carrier is bent after tyre or impact damage

• Galvanising is lost and structural corrosion has developed

• Guard mounting holes are elongated

• Step or support surface flexes excessively

• Carrier contacts the tyre during suspension movement

  

🛠️ Installation & Safety

  

• Support the trailer safely before removing undercarriage hardware

• Use correctly rated galvanised fasteners, plates and locking nuts

• Align the carrier before tightening so the guard is centred over the tyre

• Confirm tyre clearance at maximum suspension compression

• Do not stand on the plastic guard unless the carrier is designed and secured as a step support
