very easy to install can adjust to many applications long easy to see when loading problem is they bend out very very easily by only bumping them slightly while loading they bend outward have to keep re bending back in need to be stronger or have some kind of bracing if it was not for that problem i would recommend maybe ok for a smaller boat but in that case you would not require the extra length that these have. the boat im am loading is only a 26 foot center console that weighs 4300 lbs
