Not much info on the brand but it seems a decent price for four 600kg tie downs. Located in the clearance pile in front of the trade counter (Midland, WA) and had about 12 sets available this afternoon. No price on them but confirmed at the desk to be $37. Unsure if it is nationwide but they are made for Bunnings Group so the tag states.
I can't post the receipt at the moment but thought I'd give a heads up for anyone looking for a good heavy duty set. Saw them just as I was walking up to pay for these 2 x 900kg ones for $39. Although, they do have a pic of Merv on the packet.
I got my 2 x 2000kg ones for $20, and have seen them at that price a couple of times since. From bunnings.
