Thread: Old size U bolts

Refurbishing a home made dinghy trailer and having trouble finding these..need 2 sets.tried burnsco,smart marine,reproduced and supercheap auto but no joy..any ideas?

try twl ltd or trojans direct in auckand

Use 2 flat plates and use bolts

Voyager or DMW should have them.

Any half competant engineer can make them

For one of our trailors at work, I bought 4 that were too wide, cut the threaded piece off one side of all of them, then welded the remaining L shapes side by side, with a run along the top and bottom groove created by the round profile. Been through several warrants, never failed. One helluva lot better than the old bolt through a bit of flat plate trick.

Will try a couple of the local trailer shops tomorrow..

Twl might have what I need hopefully ..looking for 70mm internal measurement,100 mm long

70mm internal is a bit naff - most are about 78 or 80mm in that size which is the good old 3". The next size down that would be easily gettable I think is the 67 or 68mm internal, I guess that's 2-1/2 inch but the rest of us work in metric apparently nowadays so clamp them around 50mm internal/nominal SHS... Would 4mm each side extra clearance matter much on a little whingey dingey trailer?

Or looking at the picture, if the other three are looking like that why can't you get another spring washer and a locknut and reuse them? That one looks fine from what I can see. Or, I've wire brushed and spray galved a lot worse looking than that and they haven't fallen off yet...

Sorted twl had exactly what I needed.
