These are top quality aluminum fence rollers by Roll Guard in the U.S.: https://coyoteroller.com. I have 10 four foot rollers + 2 additional rollers that are slightly shorter and 16 "dog ear" brackets designed for wood fencing as shown in photo. Screws or bolts for the brackets are not included. If you needed different brackets or additional parts/rollers these could be purchased from them. Willing to deliver within south island.
