Yes they’re expensive but so is your gear walking off. We purchased two sets and were extremely pleased when they showed up next day. The biggest bonus was when we opened the amazon box we noticed a set of keys just loosely tossed in the box. At first in typical amazon fashion was “great someone returned these and it’s gonna suck”. But to our surprise that wasn’t the cause at all. Someone whether amazon (probably not) or rhino rack went ahead and keyed all 4 alike. Talk about grateful. I was already planning on buying new keys and lock cylinders for ease of use but it was already handled for us. Will definitely be on the lookout for more rhino rack gear in the future.A bit costly but worth the money!I really appreciate the solid cast construction.First impressions are great! Appears to be cast aluminum of some kind.The only rub is no key? Why would you ship a product with a lock and no key?This is a great product. Sturdy, unique, holds shovels and survey rods, everyone who sees this is impressed.At first I was like, man these are expensive mount, but when I received the items and checked, I was surprised that they are excellent made and easy to use. Definitely worth the money.Awesome product. Very sturdy and easy to use. Love itWorked perfect, but my products had scuff marks from the cardboard that are permanent. Rhino should have wrapped the products instead of just using cardboard. Therefore, I can’t give them a perfect score. I’m a little disappointed. I should have got a discount for a manufacturer damageLockable, well made, rock solid clamping, what else can you say? I put it on my RCI roof rack and use it with my Krazy Beaver shovel. I had to modify the attachment slightly by using t-bolts that fit in my rack and a lock nut. Easy peasy. I showed it to my buddy and he is ordering one now. Definitely recommend.
