What Users Are Saying:

rimriser screws

"We like the [precast concrete] tops and have actually installed a couple more since the first one that you worked with us on. The tops are easy to install and adjust in minutes. And in my opinion you get a more accurate setting to match existing grades. The added initial cost is minimal compared the time saved setting them. As far as safety enhancement, there is an advantage to having the built in adjustment bolts. The bolts support the tops which helps to eliminate smashed/ pinched fingers, no lifting with pry bars to place shims and no overhead safety hazards from machines and slings. The machine places it, unhooks and gets out of your way. I highly recommend your product."
