Mate Series Stainless Steel Rod & Cup Holder Backing Plate f/Round Rod/Cup Only f/3-3/4" Holes

The Mate Series Stainless Steel Rod and Cup Holder Backing Plate for Round Rod/Cup is a replacement mounting solution engineered for existing 3-3/4" hole installations. This threaded backing plate enables quick conversion from legacy cup holder setups to modern round ABS plastic combination rod and cup holders, maintaining compatibility with standard marine and recreational equipment mounting patterns.

Constructed from stainless steel, this backing plate resists corrosion in saltwater and harsh outdoor environments—a critical factor for watercraft, off-road recovery equipment, and coastal installations. The precision-threaded design accommodates the included fasteners, ensuring secure mounting without additional hardware sourcing. The 5 x 9-inch profile distributes load across the mounting surface, providing structural support for heavy-duty cup and rod assemblies subject to dynamic stress from waves, towing, or impact. Designed exclusively for round-top ABS plastic holders, this backing plate maintains dimensional accuracy with the OEM 3-3/4" hole specification.

This product is specified for marine operators, boat owners, ATV and off-road recovery specialists, and equipment technicians upgrading aging rod and cup holder systems. It eliminates the need for re-drilling or adapter fabrication, reducing downtime during equipment maintenance or refurbishment. The stainless steel construction outperforms painted steel alternatives in salt-air environments, where corrosion typically compromises standard backing plates within 12–18 months of coastal exposure.

The Mate Series backing plate represents a straightforward approach to equipment upgrades: match the existing hole diameter, confirm the round plastic cup/rod compatibility, install with supplied fasteners, and restore full functionality without structural modification. For facilities managing multiple vessels or vehicles requiring standardized cup and rod solutions, bulk availability of this part simplifies inventory and replacement workflows.
