Retractable ratchet straps

[Spare tyre]

Anyone got a recommendation for these, the sort that pull out like a seat belt

They look good for my trailer type activities or are they just guff?

I got a box of them from the USA about 5 years ago, brilliant things.

Used stainless steel ones on a boat trailer and the galv ones on my transport trailer.
Wanted to buy more and use for all my hire equipment (mini diggers, rollers, etc) but they didnt have the correct safety rating for NZ
