Product looks good and delivery was faster than expected. Thanks

Got them fast. Easy install and my boat rolls on and off so east now. Also installed a Drotto auto lock.

Everything was good except for FedEx it was supposed to arrive on a Thursday but didn't arrive until late Sunday. I needed it Friday so I could move my boat to a new marina.

Easy ordering process
