Heavy Duty Hydraulic Floor Spring for Glass Doors with Smooth Closing

Floor springs and door closers are essential hardware components for modern doors, providing reliable closing control and smooth operation for commercial, institutional, and high-end residential buildings. These devices serve different functions but share some common features and design considerations.

A floor spring, also known as a floor hinge or floor pivot, is a hydraulic or mechanical device mounted in the floor beneath the door and connected to its bottom rail or frame. It creates a pivot point that allows the door to swing open and closed smoothly, while providing a self-closing and latching action. They often have adjustable closing speed and power settings, as well as backcheck and hold-open options.

In contrast, a door closer is typically installed on the top surface of the door or the jamb, and operates by means of a spring-loaded arm or slide rail. It exerts a force to pull the door towards the frame, ensuring that it closes completely and latches securely.
