Ordered the BLIKA 36" level aluminum railing kit with 39" posts to replace the old wooden rails on our deck, and it turned out great. The panels being pre-assembled definitely saved us a ton of drill time. The black powder coat finish looks very clean, and the aluminum pickets feel thick and heavy in hand-way better quality than what we saw at the local big-box store.
Installation took me and a buddy a full Saturday. As you can tell from the pictures, the outer rim joist of our deck wasn't completely level, so we had to cut and screw down some 2x4 wood blocks underneath the base plates to shim them level before anchoring. Once everything was bolted down with the included brackets, the railing is completely rigid with no give. Solid DIY deck railing for the price.
