Question:

On your RR5K, can you tell me what the size of the ring is? Both the inner diam and the thickness of the ring material. Also, what are the length of the mounting bolts? Thank you,

I went out to the warehouse and pulled a Recessed Trailer D-Ring Tie Down with Backing Plate and Hardware, # RR5K. The ring has an inner diameter of 1-1/4 inches and an outer diameter of 2.108 inches. The ring is approximately 0.427 inches thick.

The mounting bolts are 2.42 inches long total (from the top of the bolt head to the bottom of the threaded portion). From the underneath part of the head to the bottom of the threaded portion, they measure 2.28 inches long. And they are a 3/8 inch bolt.
