Installing Brophy Light Duty Trailer Tie-Down # SR10-C in a Haulmark 7 x 16 V-Nose Trailer

The Brophy Light Duty Trailer Tie-Down, part # SR10-C, mounts with hardware of your preference using two holes that are centered at 1-1/4-inch spacing. Note that the plate and D-ring are separate parts until installed. The mounting holes themselves are of 1/4-inch diameter.

These D-ring tie downs have a safe working load limit (WLL) of 330-lbs each. Since it sounds like your application requires that these provide only horizontal hold (to keep the tables held firmly against the interior wall of the trailer without having to actually carry their weight) they should be fine for the task.

Since the 3/8-inch plywood materials inside your Haulmark is fairly thin, just to be safe I suggest you first mount a 1-1/4-inch or wider strip of wood of perhaps 1/2-inch thickness to the interior wall of your trailer using multiple wood screws and then mount the Brophy tie-downs to that strip of wood. This way you will have more depth for the mounting screws that will attach the tie-downs and you will spread the load they present across a larger portion of your trailer interior. This step may not be absolutely necessary but I would advise to err on the side of caution. In this case a 1-inch long wood screw should work well to secure the tie-downs to the wood strap and trailer.

If you prefer a higher-capacity D-ring Brophy also offers their similar SR15-C rated for a working load limit of 1600-lbs.
