This heavy-duty hydraulic Floor Spring is developed for large-format glass doors and high-load architectural entrances where controlled movement and long-term reliability are essential. Designed for professional door systems, it delivers stable closing force and precise motion control even under demanding daily use.
A dual-stage hydraulic regulation system separates the sweeping and latching phases, allowing installers to fine-tune door behavior for smooth deceleration and secure final closing. Selectable hold-open configurations provide flexibility for different traffic conditions, improving user flow in commercial and public environments.
With a reinforced internal structure and precision-machined components, this floor spring is engineered for extended service life and consistent performance across a wide temperature range. It is an ideal solution for heavy glass doors in offices, shopping centers, hotels, and transportation facilities.
