System M+ is a self-closing, fully adjustable pivot hinge system engineered for doors from 20 kg to 500 kg. Concealed inside the door and floor, it provides complete control over every part of the door's movement through three independent adjustment systems. No visible frame, no overhead closer — just a door that moves exactly as specified.
Damper Control provides adjustable hydraulic resistance on both opening and closing. On opening, a hydraulic back-check slows the door as it approaches 70° to protect walls. On closing, it delivers a smooth, controlled soft-close through the full arc of travel.
30° Speed Control governs the final phase of closing independently, ensuring the door always returns to position gently regardless of how fast it was opened or released.
Latch Control adjusts the latching force in the last degrees before closed position, guaranteeing reliable engagement of latching bolts every time. Essential for exterior doors and any door with a mortise lock.
The system is self-closing from 125° and −125°, with hold positions at 0°, 90°, and −90°. Single and double-acting configurations are available. The radial closing angle is adjustable up to 5°, and axial adjustment of ±5 mm is available from the top pivot.
The backset determines where the pivot point sits relative to the edge of the door. All three options use the same bottom pivot mechanism and are available across all weight classes.
| 70 mm Backset | 40 mm Backset | TP-R (Top Pivot Reversed) | |
|---|---|---|---|
| Pivot point | Flexible — from 70 mm to centre of door | Fixed at 40 mm from door edge | Reversed — pivot mechanism at top of door |
| Cover plates | Not available | Included — stainless steel or black | Included — stainless steel or black |
| Best for | Most residential and commercial installations. Greater flexibility in pivot placement. | Narrower doors, maximum clear opening, ADA-compliant widths from a standard slab. | Installations where floor routing is not possible or where top-access servicing is preferred. |
| System dimensions (Class AA–E) | 294.8 × 32 × 99.6 mm | 272.7 × 32 × 149.6 mm | Per TP-R specification |
| System dimensions (Class F–G) | 308.2 × 42 × 112.7 mm | 284.7 × 42 × 169 mm | Per TP-R specification |

Weight class is determined by both door weight and door width. All three configuration options are available across all eight weight classes.
| Class | Door Weight | Series | Min. Door Thickness |
|---|---|---|---|
| AA | 20 – 79 kg | M32+ | 40 mm |
| A | 80 – 119 kg | M32+ | 40 mm |
| B | Up to 159 kg | M32+ | 40 mm |
| C | Up to 209 kg | M32+ | 40 mm |
| D | Up to 279 kg | M32+ | 40 mm |
| E | Up to 349 kg | M32+ | 40 mm |
| F | Up to 429 kg | M42+ | 50 mm |
| G | Up to 500 kg | M42+ | 50 mm |
Note: For Class B through E, door width may require an upgrade to a Class G top pivot (TP.G). The FritsJurgens Selector will confirm based on your door dimensions.
All floor plates are 80 mm in diameter or width and are compatible with underfloor heating installations. The floor plate shape and finish are selected at time of order. Flush (recessed) floor plates are designed for exterior-mounted door applications — required for drop seals and weather-tight threshold details.
| Floor Plate | Bottom Gap | Radial Adjustment | Finishes | Notes |
|---|---|---|---|---|
| Square | 11 mm | ±2.5° | Stainless Steel, Black | Surface-mounted — interior applications |
| Round | 11 mm | ±2.5° | Stainless Steel, Black | Surface-mounted — interior applications |
| Flush Square | 7 mm | No | Stainless Steel | Recessed into sill — exterior-mounted doors, required for drop seals |
| Flush Round | 7 mm | No | Stainless Steel | Recessed into sill — exterior-mounted doors, required for drop seals |
