Overview
The Brophy BM12 is a heavy-duty fixed-drop ball mount designed for compatible 2" receiver hitches. Its 12" drop helps create a more level towing connection when the tow vehicle receiver sits significantly higher than the trailer coupler. The mount features a 1" hitch-ball hole, black powder-coated finish and ratings of up to 7,500 lb gross trailer weight and 750 lb tongue weight.
R&P Knowledge Hub
Compatibility: Designed for compatible 2" × 2" receiver hitches and hitch balls using a 1" diameter shank.
Trailer-Leveling Fit: A 12" drop is intended for towing combinations where the trailer coupler sits substantially below the tow vehicle receiver. Measure the actual height difference before selecting the mount.
Installation Notes: Install a properly sized and rated hitch ball using the ball manufacturer’s specified hardware and torque procedure. Secure the mount with a compatible 5/8" hitch pin and retaining clip or hitch lock.
Performance Insight: Correct ball-mount height helps the trailer tow closer to level, supporting more balanced trailer loading and predictable towing behavior.
