      Solid as. Perfect.

      Great product. Extremely heavy duty. And use on my boat in salt water conditions, no problem. Great service and delivery

      Giant Claw

      This large claw is great for wide rails, butyou're best to get the medium or small claw if you can as they are lighter and not as bulky.
