    Product Description

    This compact hydraulic Floor Spring is designed for project installations where clean aesthetics, controlled motion, and reliable closing performance are required for glass door systems. It is a practical choice for interior commercial entrances that need stable door control without oversized hardware.

    A dual-zone speed adjustment allows installers to independently tune the sweep and latch phases. The result is a smooth approach, controlled deceleration, and dependable latching at the end of travel, helping reduce edge impact and long-term wear on patch fittings and door frames.

    With selectable hold-open settings and a long-cycle durability reference, this floor spring supports specification-driven builds across offices, retail interiors, and public spaces where consistent daily operation matters.
