Description
Safetech Fixed Tension Hinges – AlfaHinge – SHF-90L-1
The Safetech AlfaHinge SHF-90L-1 is a pair of single-leg fixed-tension self-closing gate hinges designed for pedestrian, garden and pool-gate applications where reliable automatic closing is required.
Manufactured from durable fibre-reinforced engineered polymer with rust-resistant stainless-steel pins and springs, the SHF-90L-1 provides a corrosion-resistant and economical alternative to conventional metal gate hinges.
The SHF-90L-1 features Safetech’s compact single-leg mounting design, vertical gate adjustment and a factory-set self-closing spring tension that requires no tension adjustment during installation.
🚪 Fixed-Tension Self-Closing Design
The SHF-90L-1 incorporates an internal fixed-tension spring designed to automatically return the gate towards the closed position after it has been opened.
Unlike adjustable-tension gate hinges, the spring tension is factory set and does not require adjustment during installation.
This provides a simple and reliable self-closing solution for compatible lightweight pedestrian gates.
🔄 Automatic Gate Closing
When the gate is opened and released, the internal spring assists the gate back towards its closed position.
When correctly installed with a suitable self-latching gate latch, the SHF-90L-1 can form part of a self-closing and self-latching gate system.
Typical applications include:
- Pedestrian gates
- Garden gates
- Side access gates
- Residential gates
- Pool gates
- Fence gates
- Compatible commercial pedestrian gates
🦵 Single-Leg Mounting Design
The defining feature of the SHF-90L-1 is its single-leg mounting arrangement.
This provides a more compact mounting configuration than the two-leg SHF-90L while retaining the same AlfaHinge fixed-tension self-closing principle.
The single-leg configuration can be particularly useful where the gate or post design does not provide sufficient mounting space for the additional leg of the SHF-90L.
🆚 SHF-90L-1 vs SHF-90L
Safetech manufactures two fixed-tension versions of the standard AlfaHinge:
SHF-90L-1
- Single-leg mounting design
- Fixed self-closing tension
- Vertical adjustment
- 28kg holding capacity
- 15kg closing capacity
SHF-90L
- Two-leg mounting design
- Fixed self-closing tension
- Vertical adjustment
- 28kg holding capacity
- 15kg closing capacity
The correct version should be selected according to the required mounting arrangement and gate construction.
💪 28kg Holding Capacity
Safetech specifies a maximum holding weight of 28kg for the AlfaHinge range under its standard test conditions.
Holding capacity refers to the gate weight the hinge pair is designed to support.
Gate width and height also influence the load placed on the hinges and should always be considered when selecting suitable gate hardware.
⚙️ 15kg Self-Closing Capacity
Safetech specifies a maximum self-closing gate weight of 15kg under its standard test conditions.
The holding and closing capacities are different specifications.
For the SHF-90L-1:
- Maximum Holding Weight: 28kg
- Maximum Self-Closing Weight: 15kg
For installations requiring reliable automatic closing, the 15kg closing capacity is the important rating when determining suitability.
↕️ Vertical Adjustment
The SHF-90L-1 provides vertical adjustment to assist with correctly positioning the gate during installation.
This allows the installer to fine-tune the gate height and alignment relative to the latch and surrounding fence.
Correct vertical alignment is particularly important on self-closing gates because the gate must consistently return to the correct position for the latch to engage.
🧱 Fibre-Reinforced Polymer Construction
Safetech manufactures the AlfaHinge range from durable fibre-reinforced engineered polymer.
This provides a strong hinge body while eliminating the corrosion problems associated with conventional unprotected steel gate hinges.
The polymer construction also provides a clean modern appearance suitable for contemporary gate and fencing systems.
☀️ UV-Stabilised Construction
The AlfaHinge polymer is UV stabilised to help resist deterioration and fading caused by prolonged exposure to sunlight.
This makes the hinge well suited to outdoor gates where the hardware is continually exposed to Australian weather conditions.
🔩 Stainless-Steel Pins & Springs
The engineered polymer hinge body is combined with rust-resistant stainless-steel components.
These include:
- Stainless-steel hinge pins
- Stainless-steel spring components
The combination provides a corrosion-resistant hinge system designed for external gate applications.
🌦️ Designed for Outdoor Use
The combination of UV-stabilised polymer and corrosion-resistant stainless-steel components makes the SHF-90L-1 suitable for outdoor gate installations.
Unlike conventional unprotected steel hinges, the polymer hinge body will not rust.
This makes the AlfaHinge particularly useful for residential gates continually exposed to weather.
🏊 Suitable for Pool Gate Applications
Safetech lists the fixed-tension AlfaHinge range for compatible pool-gate applications.
The fixed spring tension automatically returns the gate towards the closed position so a compatible self-latching gate latch can engage.
Any pool-gate installation must still be correctly designed, installed and tested in accordance with applicable Australian pool-barrier regulations and requirements.
The complete gate system — not simply the hinges — determines whether the installation is compliant.
🔗 Ideal with Self-Latching Gate Hardware
The SHF-90L-1 can be combined with a compatible self-latching gate latch to create a self-closing pedestrian gate system.
When the gate is released, the hinge spring returns the gate towards its closed position, allowing the latch to engage.
Correct hinge positioning, gate alignment and latch installation are essential for reliable operation.
🏠 Ideal for Lightweight Pedestrian Gates
The AlfaHinge SHF-90L-1 is particularly suitable for lightweight pedestrian gates.
Typical applications include:
- Aluminium pedestrian gates
- Steel pedestrian gates
- Timber pedestrian gates
- Side access gates
- Garden gates
- Pool gates
- Residential fence gates
- Self-closing access gates
🔧 Excellent Replacement Hinge
The AlfaHinge range is also suitable for compatible replacement applications where conventional hinges have become damaged, seized or corroded.
Its polymer and stainless-steel construction provides an economical corrosion-resistant replacement solution.
The single-leg SHF-90L-1 can be particularly useful where available mounting space is limited.
Existing mounting positions, gate dimensions and gate weight should always be checked before replacing another hinge system.
🎨 Clean Black Finish
The SHF-90L-1 is supplied in a black finish that complements common aluminium, steel and timber gate designs.
Its compact polymer construction provides a clean appearance without the bulk associated with many traditional self-closing hinge systems.
📦 Supplied as a Pair
The SHF-90L-1 is supplied as a pair of hinges for one gate.
A standard installation consists of:
- 1 × Upper SHF-90L-1 Fixed-Tension Hinge
- 1 × Lower SHF-90L-1 Fixed-Tension Hinge
The pair works together to support the gate and provide the required self-closing action.

Compatibility
The Safetech AlfaHinge SHF-90L-1 is designed for compatible pedestrian and swing gates.
Suitable applications include:
- Aluminium gates
- Steel gates
- Timber gates
- Pedestrian gates
- Garden gates
- Side access gates
- Self-closing gates
- Compatible pool gates
The single-leg mounting configuration makes the SHF-90L-1 particularly useful where mounting space or gate construction makes the two-leg SHF-90L unsuitable.
Gate dimensions, weight and installation geometry must remain within the appropriate hinge capacity.
⚠️ Please Note
Safetech specifies a maximum holding weight of 28kg and a maximum self-closing weight of 15kg for the AlfaHinge range.
These ratings are based on a standard test gate measuring approximately 900mm wide x 1200mm high.
Gates exceeding these dimensions can place additional leverage on the hinges and may reduce their effective holding and self-closing capacity.
The 28kg holding capacity should not be confused with the 15kg closing capacity. For a self-closing installation, the gate must remain within the appropriate closing capacity.
The SHF-90L-1 has fixed factory-set spring tension. If adjustable closing tension is required, a suitable Safetech adjustable-tension hinge should be selected instead.
The SHF-90L-1 is the single-leg model. For a two-leg mounting configuration, select the Safetech SHF-90L.
For pool-gate applications, the complete gate, hinge and latch installation must comply with all applicable pool-barrier regulations and requirements.
