Website detail shows 'Made from 50x50mm heavy duty galvanised steel box section - panel rails sleeve into converters' - however I trust it is actually aluminium - and that if it is 50x50 and sleeves (tightly/firmly/securely) onto a 40x40 rail then it should have aluminium wall thickness of 5mm - hope that is correct - and I can then have confidence buying online. regards Gerry
Hi Gerry, the aluminium wall thickness of this
gate converter is 4mm and is designed to be used with our
aluminium security panels - they are very popular and work extremely well to provide a solution for needing an extra wide security gate without the cost of a custom panel.
