Hey Everyone! Pool season is finally here in Central NC. I have question for the group. We have wedding cake steps that I weight down each year with 2 EA 4" PVC pipes with caps filled with sand. My steps have no shelf or tray to put weights on so I have been mounting them underneath with zip ties that come up through the holes in the stair treads. These last almost a whole season, but they seem to break every year with about a month left to go. Does anyone have an idea of what I could use besides zip ties that won't breakdown and break apart before the end of the season?
