FREE SWING

System ONE

The Single Action System

Up to 500 kg  ·  Single-acting

The Hold-Open System

Up to 500 kg  ·  Single or double-acting

Which System Is Right for You?

FritsJurgens makes three pivot systems. Each is fully concealed inside the door and floor. The difference is in how the door moves — and how much control you need over that movement.

40 mm backset Fixes the pivot point as close to the door edge as possible, maximising clear opening width. The right choice for narrower doors, openings where every millimetre of clearance matters, or projects requiring ADA-compliant clear widths from a standard door slab. Available on all three systems.
70 mm backset The standard and most common choice. The pivot point can be positioned anywhere from 70 mm to the centre of the door, offering greater flexibility for a wide range of door widths and frame configurations. If you are unsure which backset to specify, start here. Available on all three systems.
Best for A pivot door that stays where you put it. No mechanism to configure, no closing force to manage. Full 360° revolving capability. Passages and open-plan spaces where the door needs defined hold positions — open, closed, or in between. Doors that need to close themselves, every time — with adjustable control over exactly how they do it.
