Simpson Strong Tie connectors are simply the best and most stylish on the market. They are 100% metal and the railing breaks before the connector breaks. Any similar poly/plastic items can work but are not as reliable. My top deck is 10 feet off the ground and I used Simpson ties for security and durability (the weather won't weaken them over the years). If you want peace of mind, you won't regret purchasing Simpson Strong Ties. I like to do projects right once and don't worry or do them again 2 or 3 years later. This is not the best option for stair railings. And I hope Simpson can come up with something for the corner railing, but I'll adjust the quality where I can.
