A floor spring combo set is a complete hardware kit designed to support, pivot, and automatically close heavy doors, usually frameless glass doors. The floor spring is concealed inside a metal box "cemented" into the floor, offering a clean, minimalist aesthetic.
The floor spring operates using a hydraulic system that manages heavy door weights (often up to 120 kg or more) with ease.
- Opening (Storing Energy)
As you push the door, a heart-shaped cam rotates, compressing a powerful internal spring. This stores the energy required to pull the door back later.
- The Hydraulic "Check"
The interior is filled with high-grade oil. As the spring tries to push the door closed, the oil is forced through narrow valves. This "dampening" prevents the heavy glass from slamming.
- Double Action Swing
Unlike regular door closers, floor springs allow the door to swing both ways (inward and outward) and usually feature a "hold-open" at 90 degrees.
