Pulled them out of a 2012 Cobalt for a neighbor last year. Couple of them didn't work correctly, he wanted them gone. It probably had to due their age and no maintenance IMO. They were stiff as a preachers prick at a boy's home.
What do they look like on? I try to avoid things that are proprietary and multi function in the event they create a bigger hole in the boat, go under as a company and now I cannot just replace them with a regular cleat!
My brother has this funky system of flat bumpers with toggle straps on backside of them and elastic straps for lines that use caribeaners on the ends. He’s always fussing with his system while I’m tied up already and pumping fuel for 10 min before he’s done.
There is a reason why Taylor made bumpers have been made the same for ages. And why dock lines have common standards too.
If it ain’t broke, don’t fix it.
