We have one poster here who regrets having to rely on the Saftron handrails as he finds them very unattractive compared to the handrails placed during construction. Installing the cups during construction, yet not using them unless needed, solves this problem. There are many fancy artsy rails out on the market now if you look around.
You mention a fence around the pool- Have you considered an autocover instead? May not cost that much more than a fence. We love ours. One turn of the key and the cover opens and shuts in seconds. Chemicals last longer, the pool stays warmer when covered overnight, and the pool stays cleaner. With small kids as you have it could be a huge weight off your mind to know the pool is off limits and safe.
