I pre-installed on a board as a mat before fixing permanently on a wall outside - well took me !!! - Indeed, the distance between the two hinges is not 380 mm as specified on the doc (and on the bracket itself) but 360 mm !!! Phew, good thing I had not done the holes and in the chemical sealing !! facade. And the removable arm length is not sufficient to secure a winch Timbertech ESV600 along 380 mm. The maximum length available for setting in "110" position is 330 mm. This information should be specified in the documentation. Apart from these two points, the product seems solid.
