What is this?

I have a 79 EZLoader trailer that has a "U" tube between the last set of rollers. What is the purpose of this?

Looks like it's there to prevent the roller assembly from flipping upside down. Does it rest against the axle subframe when the boat is off the trailer?

Sorry I do not know. I just bought this a couple weeks ago. It has a 19 ft boat on it. I bought it with the thought of modifying the trailer to fit my 24 ft boat.

Its probably there to stop the roller brackets from tilting too far and allowing the bow to contact the trailer frame. Sort of like a kick stand effect. My Shoreline has one on the frame that's adjustable, it attaches on each side between the roller bracket pivot bolts.

When the trailer is on the ramp, and the boat is just making contact, it keep the rollers from just pushing downward letting the boat make contact with the face of he roller brackets or frame.
The roller brackets on mine rest on the stand, thus keeping them at the right angle to start the boat up onto the trailer.

the set up at one time may have been tail heavy, when sitting free, to keep the bow from tilting all the way up. saving the lower unit from hitting the ground.

On one of mine it's actually got a spring loaded rear crossmember that acts like a kick stand. It does keep the boat from tilting back but not so much as it keeps the trailer from squatting when the boat loads.
The one above is attached to the rollers not the frame, so it not only limits travel, it forces both rear roller assemblies to move a one.
I could see that as an aid to aligning the boat centered on the trailer.
