Made with quality steel and stainless U bolts, so strong enough to center a boat onto a trailer as designed. A steel fabricator told me he could not buy the materials for the retail price, let alone make it.
these trailer guides are very good quality..their versatle mounting optins and hardware are perfect for my 14ft deep transom auminum boat and make loading the boat easy even in high winds...they are sturdy, reliable and all contact points are rubber and plastic preventing scratching to your boat...heavy duty frames with all stainless hardware makes them a really good design..five stars
