What you're actually buying
This is the hanger arm itself, not the flap - stainless so it doesn't rust out and streak the flap or the bumper. Spring loaded means the arm gives when you back into a dock plate or catch a curb, then springs back instead of bending or snapping a weld.
Bolt spacing on the mounting holes is 2-1/2 inches, which is the common spacing on most straight hangers you'll find behind semi-trailers and tractors running 30 inch drop flaps. Pair means you get driver and passenger side, both the same part since these are straight (not offset left/right).
Comes up a lot on van trailers, flatbeds, and tractor mud flap brackets where the previous hanger rusted through or got torn off backing into something.
How the cross numbers line up
FD002, MFHS10S, and PN-3-C-001-430 all show up because they're built to the same 30 inch length, same 2-1/2 inch bolt spacing, and same spring-loaded design - different brands slapping their own part number on essentially the same hanger geometry.
Where guys get burned is bolt spacing. There's another common spacing out there (3 inch) that looks identical from ten feet away but won't line up with your existing holes without redrilling. Also check hanger length - 24 inch and 30 inch versions get mixed up in bins all the time.
Surest way to confirm: pull the old hanger, measure bolt hole center-to-center, measure overall length, and check if it's spring loaded or solid arm. If you've got a VIN for the trailer, even better - cross it against the mounting bracket if there's a manufacturer tag.

Frequently asked questions
Does PS-BD.01.UN.011 fit my trailer?
Depends on your bolt spacing and hanger length, not the trailer brand or model year alone. Pull the old hanger, measure the hole spacing (should be 2-1/2 inches center to center) and confirm it's a 30 inch spring-loaded arm. If that matches, you're good - if you're not sure, send us the numbers off the old part.
Is this the same as the Fortunes MFHS10S?
Same length, same bolt spacing, same spring-loaded setup - so functionally it crosses over. It's not the identical Fortunes part, it's an aftermarket equivalent built to the same spec. Confirm your bolt pattern matches before ordering since that's the main thing that trips people up.
Can I use one of these on the tractor and one on the trailer, mixed brands?
Sure, as long as both sides match your bolt spacing and hanger length - the hanger doesn't care what brand's on the flap or the other side, they don't have to match each other. Just get the mounting geometry right on each end.
