A Hydraulic Floor Spring is a heavy-duty door control system installed beneath the floor to provide smooth, automatic closing for glass, aluminum, or wooden doors. Designed for high-traffic commercial spaces, it ensures controlled opening and closing with adjustable speed and latching action. Its concealed installation maintains a clean, modern appearance while delivering strong load-bearing performance. Built with durable hydraulic technology, a floor spring enhances safety, prevents slamming, reduces wear, and offers reliable, long-lasting operation in demanding environments.
