Pivot doors create a clean architectural appearance and can support much larger and heavier doors than standard butt hinges. However, choosing the correct pivot system involves more than checking the maximum weight rating.
Door width, finished weight, thickness, pivot position, floor construction, locking and whether the door needs to self-close all affect the final selection.
This guide compares three popular options in Australia: FritsJurgens System M+, JNF hydraulic pivots and Lockwood pivot kits.
What Is a Pivot Door?
A conventional door is supported by hinges fixed along one vertical edge. A pivot door rotates around a top and bottom pivot point.
The bottom pivot normally carries most of the door’s weight, while the top pivot keeps the door aligned. The pivot point can be positioned close to the edge or further towards the centre of the door.
Moving the pivot point further inward creates the distinctive pivot-door movement, but it also leaves a short section of the door behind the pivot. This affects clear opening width, side clearances, handle positioning and sealing.
Pivot doors are commonly used for:
- Large entrance doors
- Wide architectural doors
- Heavy timber or metal-clad doors
- Internal feature doors
- Commercial aluminium or glass doors
The Main Types of Pivot System
Free-Swing Pivot Kits
A free-swing pivot supports the door but does not automatically close it.
The door stays where it is left unless it is manually closed or fitted with a separate closer.
Lockwood pivot kits are a common example. They are simple, durable and comparatively affordable, making them suitable for internal feature doors or commercial doors that do not need integrated hydraulic control.
Hydraulic Pivots Concealed in the Door
With this type of system, the hydraulic mechanism is installed inside the bottom of the door.
Depending on the model, it can provide:
- Controlled self-closing
- Adjustable closing speed
- Hydraulic opening resistance
- Final latching control
- Single- or double-action operation
- Hold-open positions
FritsJurgens System M+ and several JNF systems use this design.
Traditional Floor Springs
A floor spring places the hydraulic closer inside a box recessed below the finished floor.
Floor springs are widely used on commercial timber, aluminium and glass doors. They provide reliable closing control but require more floor preparation than an in-door pivot system.
They must also be coordinated with waterproofing, underfloor heating, plumbing, electrical services and finished floor levels.
FritsJurgens vs JNF vs Lockwood
FritsJurgens System M+
FritsJurgens System M+ is a premium concealed hydraulic pivot system designed for large and heavy architectural doors.
It provides adjustable:
- Opening damping
- Closing speed
- Final latching force
The system can be configured for single- or double-action doors and is available in different load classes for doors from approximately 20kg up to 500kg.
Minimum door thickness is generally:
- 40mm for systems up to approximately 350kg
- 50mm for the largest weight classes
FritsJurgens is particularly suitable for:
- Oversized entrance doors
- Heavy timber, steel or clad doors
- Projects requiring smooth, controlled movement
- Doors that must reliably engage a latch
- Projects where a large floor-spring box is undesirable
Approximate hardware pricing is generally around $2,500 to $4,500 or more, depending on the model, weight class, finish and pivot position.
JNF Hydraulic Pivots
JNF offers hydraulic pivot systems ranging from compact products for lighter internal doors to heavy-duty systems for large architectural doors.
A smaller JNF hydraulic pivot may suit a timber door weighing up to approximately 60kg. These systems commonly provide adjustable closing and a 90-degree hold-open position.
They are well suited to:
- Internal timber doors
- Smaller architectural pivot doors
- Projects requiring hydraulic closing at a lower price point
- Applications where a traditional floor-spring box is not practical
Entry-level JNF hydraulic systems are generally priced at a few hundred dollars.
JNF also offers heavy-duty systems rated for doors up to approximately 350kg. These larger systems are closer to FritsJurgens in both capacity and project type, with hardware pricing commonly starting in the mid-$2,000 range.
Lockwood Pivot Kits
Lockwood pivot kits are mechanical free-swing systems for timber and aluminium doors.
Common options include:
- A kit rated to approximately 115kg
- A heavy-duty kit rated to approximately 200kg
These systems include the top and bottom pivot components required to support the door, but they do not provide hydraulic closing.
Lockwood pivot kits are suitable when:
- The door should move freely
- Automatic closing is not required
- A separate closer will be installed
- The project needs a simple and economical pivot solution
Approximate pricing is generally around $200 to $300 for the pivot kit.

What Is the Real Pivot Door Weight Limit?
There is no single pivot door weight limit.
The correct system depends on:
- Finished door weight
- Door width
- Pivot position
- Door height
- Door construction
- Centre of gravity
- Internal or external use
A wide door creates more leverage than a narrow door of the same weight. This means a system should never be selected from the kilogram rating alone.
Always use the completed door weight, including:
- Cladding
- Glass
- Steel reinforcement
- Pull handles
- Locks
- Edge trims
- Drop seals
Self-Closing vs Free-Swing
A free-swing pivot allows the door to move without automatic closing. Lockwood pivot kits are a typical example.
A self-closing pivot uses a spring and hydraulic mechanism to return the door to the closed or centred position. FritsJurgens and JNF hydraulic systems are typical examples.
Self-closing is usually preferred when the door must:
- Engage a latch
- Control draughts
- Remain closed for security
- Return to a consistent position
- Avoid being left partly open
Hold-open is different from free-swing. A hold-open system still has hydraulic closing control but temporarily holds the door at a set angle, usually around 90 degrees.
Pivot Hinge vs Floor Spring
An in-door hydraulic pivot contains the main mechanism inside the door and normally requires only a small floor plate.
Advantages include:
- Minimal visible hardware
- Less floor excavation
- Easier coordination with many finished floors
- Reduced conflict with underfloor services
- A clean architectural appearance
The main limitation is that the door must be thick enough and accurately machined to accept the mechanism.
A traditional floor spring contains the closer below floor level.
Advantages include:
- Proven commercial performance
- Options for timber, aluminium and glass doors
- A wide range of closing functions and accessories
- Availability of specialised fire and smoke door models
The main disadvantages are the larger floor recess, more complex installation and the need for future access through the cover plate.
What Does a Complete Pivot Door Cost?
Pivot hardware is only one part of the total project cost.
A complete pivot door may also require:
- A custom door leaf
- Internal steel reinforcement
- Precision machining
- Structural head framing
- A suitable frame
- Locks and cylinders
- Pull handles
- Automatic drop seals
- Thresholds and weather seals
- Electrical access-control preparation
- Freight, lifting and installation
A simple internal pivot door may cost several thousand dollars once the door, machining and installation are included.
A premium custom entrance door using high-end hydraulic hardware may cost anywhere from roughly $6,000 to well over $15,000, depending on size, construction, finishes and installation requirements.
Very large, imported, metal-clad or heavily engineered doors can cost considerably more.
What Your Builder Needs to Know Before Ordering
Before purchasing pivot door hardware, confirm the following:
- Finished door height, width and thickness
- Completed door weight
- Door construction and cladding
- Required pivot position
- Single- or double-action opening
- Free-swing or self-closing operation
- Hold-open requirements
- Lock and latch details
- Internal or external location
- Floor construction and finished floor height
- Location of underfloor services
- Structural support at the head
- Required gaps and clear opening width
- Threshold and sealing details
- Any fire, smoke, access or emergency-exit requirements
The door manufacturer should also receive the exact machining template for the selected system. Do not prepare the door using dimensions from a similar-looking pivot product.
Common Ordering Mistakes
- Selecting the system from weight alone
- Ordering before the completed door weight is known
- Buying a free-swing kit when self-closing is required
- Ignoring the minimum door thickness
- Choosing the pivot position after the door has been made
- Failing to coordinate locks, drop seals and pivot mortises
- Not checking underfloor heating or services
- Assuming a pivot door will seal like a standard hinged door
- Failing to provide suitable structural support at the head
Which System Should You Choose?
Choose FritsJurgens System M+ when the door is large, heavy or architecturally significant and smooth, adjustable closing movement is a priority.
Choose a JNF hydraulic pivot when controlled closing is required and the door falls within the selected model’s weight, width and thickness limits.
Choose a Lockwood pivot kit when the door should free-swing and integrated hydraulic closing is not required.
Choose a traditional floor spring when the project calls for a conventional commercial closer below floor level or requires a particular tested door configuration.
