They are cheap alright, and sure know how to charge for accessories. I always used to leave them in place on all the accessories I was installing, but decided as long as the instructions say to discard them, may as well.
I left mine on as I never got directions with the dozen I purchased... Also when my rear cab is off the rubber blocks help keep the clamp closed.
Cheap Mmmm not here in Canada, $18-20.00 per clamp not including tax. On line was like $8.50 to my door all in. Ridiculous really....
