Overview
The Brophy BP05 is a zinc-plated steel backing plate used under the trailer floor when installing compatible recessed D-ring tie-down anchors. It reinforces the mounting area beneath Brophy RR05-style installations and gives the anchor a broader support surface than the floor material alone.
R&P Service Insight
Backing plates matter when tie-down anchors are mounted through wood, steel, or composite trailer flooring. The plate helps spread load across the mounting area, but the final installation strength still depends on the anchor, hardware, trailer floor condition, and mounting method.
- Check the anchor: Match this backing plate to the recessed D-ring anchor pattern before drilling.
- Check the floor: Do not install over rotted, cracked, thin, or unsupported flooring.
- Check the hardware: Mounting hardware is not included; use appropriate 3/8" hardware for the installation.
R&P Knowledge Hub
Compatibility: Designed for Brophy RR05 recessed D-ring tie-down anchor installations. Brophy also references BP05 as a backing plate for RR05 and RRS5 applications.
Trailer / System Fit: Used on trailers requiring a reinforced 4-bolt recessed D-ring mounting location where measurements and bolt pattern match.
Installation Notes: The BP05 installs beneath the trailer floor. Confirm the 6-1/2" square plate size, 3-5/16" center opening, and 3/8" bolt holes before ordering.
Performance Insight: A backing plate helps distribute mounting force under the anchor area. Do not treat the backing plate alone as the complete tie-down system or as a capacity rating.
Brand & Fitment Note
Selling Brand: Brophy
Application Reference: RR05 and RRS5 references are compatibility/application references for matching Brophy recessed tie-down anchor installations.
What This Means: This listing is for one Brophy BP05 backing plate only. It is not a complete D-ring kit unless a separate kit is specifically listed.
Before Ordering: Verify measurements, bolt pattern, trailer floor condition, anchor model, and hardware requirements before installation.
R&P Repair Insight
When replacing or adding trailer tie-down points, confirm the complete mounting stack before ordering parts. The backing plate, D-ring anchor, trailer floor, and bolts all work together as a system.
- Plate Match: Compare the existing plate or anchor opening to the 6-1/2" square BP05 dimensions.
- Hardware Match: This plate uses 3/8" bolt holes; bolts, washers, and nuts are not included.
- Load Path: Tie-down strength depends on the full installation, not the backing plate by itself.
