Top Guard drain inlet protection devices, by ERTEC, are thoughtfully engineered to balance the tradeoff between street safety by allowing flow, and sediment collection. Top Guard devices stay above ground and deliver many benefits: installation, maintenance, inspections, and removal are much easier and faster. And because grates do not need to be removed, worker’s comp claims are minimized. Total costs are significantly reduced.
