This is a very substantial, well designed, and high-quality product.  The hard work involved in installing it is all about drilling the holes required for the supporting bolts... in our case, into incredibly hard concrete, which is a severe test for whatever hammer drill any amateur might have!  Thanks to very clear instructions, and meticulous accounting and description of all the necessary parts, the assembly thereafter was easy enough, quick, and rewarding.  We wanted something modern and functional but in keeping with our granite-walled house (known locally as "the castle").  This works surprisingly well, especially as it goes well with black wrought iron gates.   Very satisfied so far.  Yet to test it in heavy snow or wind, but it seems rock solid.
