Floor-Mounted Adjustable Double Acting Spring Hinge (Commercial Grade)

Designed for commercial and heavy-duty doors that must swing in both directions and automatically return to center.
This floor-mounted hinge is intended for applications where a concealed, high-capacity solution is required and surface-mounted or overhead hardware is not suitable.

⚠️ Not recommended for most residential or light-duty doors.
If you are unsure whether your door requires a floor-mounted system, review the checklist below or contact our support team before ordering.

Product Overview

This floor-mounted adjustable double acting spring hinge is engineered for demanding commercial environments where durability, control, and a clean appearance are essential. By mounting below the floor surface, the hinge remains concealed while providing controlled, bi-directional door movement and reliable return-to-center functionality.

Adjustable spring tension allows installers to fine-tune door resistance and closing force after installation. The ball-bearing design promotes smooth operation and long-term performance in high-traffic environments such as restaurants, commercial interiors, and architectural door applications.

Because this hinge requires precise alignment and floor preparation, it is best suited for experienced installers and professional installations.
