Description
Safetech Non-Tension Hinges – AlfaHinge – SHN-90L-1
The Safetech AlfaHinge SHN-90L-1 is a pair of compact single-leg neutral-tension gate hinges designed for pedestrian and swing gates where smooth, unrestricted manual movement is required without automatic self-closing action.
Manufactured from durable fibre-reinforced engineered polymer with rust-resistant stainless-steel pins, the SHN-90L-1 provides a corrosion-resistant and economical alternative to conventional metal gate hinges.
The SHN-90L-1 features Safetech’s compact single-leg mounting arrangement, vertical gate adjustment and a maximum holding capacity of 28kg under Safetech’s standard test conditions.
🚪 Neutral / Non-Tension Design
The SHN-90L-1 is a neutral-tension gate hinge.
Unlike Safetech’s fixed-tension and adjustable-tension hinges, it does not incorporate a spring designed to automatically return the gate to the closed position.
This allows the gate to swing freely and makes the SHN-90L-1 ideal for manual pedestrian gates where automatic self-closing operation is not required.
🔄 Smooth Manual Gate Movement
Without an internal closing spring, the SHN-90L-1 allows the gate to move freely as it is manually opened and closed.
This makes it particularly suitable for:
- Pedestrian gates
- Garden gates
- Side access gates
- Residential gates
- Fence gates
- Manual swing gates
- Gates using a separate closing device
- Applications where automatic closing is not required
🦵 Compact Single-Leg Design
The defining feature of the SHN-90L-1 is its single-leg mounting arrangement.
This provides a more compact mounting configuration than the two-leg SHN-90L while retaining the same neutral-tension AlfaHinge design.
The single-leg configuration can be particularly useful where available mounting space is limited or where the gate and post design does not suit the additional mounting leg of the SHN-90L.
🆚 SHN-90L-1 vs SHN-90L
Safetech offers its neutral-tension AlfaHinge in two mounting configurations.
SHN-90L-1:
- Single-leg mounting design
- Neutral / non-tension operation
- No self-closing spring
- Vertical adjustment
- 28kg maximum holding capacity
SHN-90L:
- Two-leg mounting design
- Neutral / non-tension operation
- No self-closing spring
- Vertical adjustment
- 28kg maximum holding capacity
The correct version can be selected according to the gate construction and available mounting space.
🆚 Neutral vs Fixed Tension
Safetech also produces the SHF-90L-1, which uses a similar single-leg AlfaHinge configuration but incorporates a fixed self-closing spring.
SHN-90L-1:
- Neutral / non-tension
- No self-closing action
- Free manual gate movement
- 28kg maximum holding capacity
SHF-90L-1:
- Fixed self-closing tension
- Factory-set spring
- 28kg maximum holding capacity
- 15kg maximum closing capacity
Choose the SHN-90L-1 where unrestricted manual gate movement is required.
Choose the SHF-90L-1 where automatic self-closing action is required.
💪 28kg Maximum Holding Capacity
Safetech specifies a maximum holding weight of 28kg for the SHN-90L-1 hinge pair under its standard test conditions.
Because this is a neutral-tension hinge, there is no self-closing weight rating.
For the SHN-90L-1:
- Maximum Holding Weight: 28kg
- Self-Closing Function: No
- Closing Weight Rating: Not Applicable
📐 Gate Dimensions Affect Capacity
Gate weight should not be considered independently from the dimensions of the gate.
Safetech’s quoted holding capacity is based on a standard test gate measuring approximately 900mm wide x 1200mm high.
A wider or taller gate creates additional leverage on the hinge system and supporting post.
For gates outside the standard test dimensions, hinge suitability should therefore be assessed according to the complete gate design rather than weight alone.
↕️ Vertical Adjustment
The SHN-90L-1 provides vertical adjustment to assist with correctly positioning the gate during installation.
This allows the installer to fine-tune gate height and alignment relative to the latch, gate stop and surrounding fence.
Vertical adjustment can assist with achieving:
- Correct gate height
- Consistent ground clearance
- Accurate latch alignment
- Even gate gaps
- Improved overall gate alignment
🧱 Fibre-Reinforced Polymer Construction
Safetech manufactures its AlfaHinge range from durable fibre-reinforced engineered polymer.
The reinforced construction provides strength while avoiding the corrosion problems commonly associated with conventional unprotected steel gate hinges.
The polymer body also provides a clean appearance that complements modern aluminium, steel and timber gate systems.
☀️ UV-Stabilised Construction
The AlfaHinge polymer is UV stabilised to resist fading and deterioration caused by prolonged exposure to sunlight.
This makes the SHN-90L-1 particularly well suited to outdoor gate installations exposed to Australian weather conditions.
🔩 Rust-Resistant Stainless-Steel Pin
The engineered polymer hinge body is combined with a rust-resistant stainless-steel hinge pin.
The combination of engineered polymer and stainless steel provides a corrosion-resistant hinge system specifically designed for external gate applications.
🌦️ Designed for Outdoor Use
The SHN-90L-1 provides an excellent alternative to conventional unprotected steel hinges for outdoor gate installations.
Its engineered polymer body will not rust, while the stainless-steel hinge pin provides additional corrosion resistance.
This makes the AlfaHinge particularly useful for pedestrian gates continually exposed to weather.
🏠 Ideal for Aluminium Gates
The compact black AlfaHinge is particularly well suited to modern aluminium pedestrian gates.
Its single-leg mounting configuration provides a neat installation while the black polymer body complements commonly used powder-coated aluminium gate frames and posts.
Typical applications include:
- Aluminium pedestrian gates
- Aluminium slat gates
- Aluminium batten gates
- Aluminium privacy gates
- Aluminium fence gates
- Custom fabricated aluminium gates
🪵 Suitable for Metal & Timber Gates
Safetech specifies the SHN-90L-1 for compatible metal and timber gate applications.
Suitable gate materials include:
- Aluminium
- Steel
- Timber
The gate and supporting post must provide a structurally suitable mounting surface for the hinge and fixing hardware.
🚶 Ideal for Manual Pedestrian Gates
The SHN-90L-1 is particularly suited to gates intended to remain wherever the user positions them rather than automatically returning to the closed position.
Typical applications include:
- Residential pedestrian gates
- Side access gates
- Garden gates
- Utility access gates
- Fence gates
- Manual access gates
- Compatible commercial pedestrian gates
🔗 Compatible with Gate Latches
The SHN-90L-1 can be combined with a wide range of compatible gate latches.
Because the hinge does not automatically return the gate to the closed position, the user manually closes the gate before the latch engages unless a separate gate-closing device is installed.
This makes the hinge ideal where self-closing operation is unnecessary.
🔧 Excellent Replacement Hinge
The AlfaHinge range is also well suited to compatible replacement applications where conventional hinges have become worn, damaged, seized or corroded.
The SHN-90L-1’s compact single-leg configuration can be particularly useful where mounting space is limited.
Gate weight, dimensions and existing mounting conditions should always be checked before replacing another hinge system.
🎨 Clean Black Finish
The SHN-90L-1 is supplied in a black finish designed to complement common aluminium, steel and timber gate systems.
Its compact polymer construction provides a clean and unobtrusive appearance without the bulk associated with many traditional gate hinges.
📦 Supplied as a Pair
The SHN-90L-1 is supplied as a pair of neutral-tension hinges for one gate.
A standard installation consists of:
- 1 × Upper SHN-90L-1 AlfaHinge
- 1 × Lower SHN-90L-1 AlfaHinge
The pair works together to support the gate while allowing unrestricted manual swing movement.

⚠️ Please Note
The SHN-90L-1 is a neutral / non-tension hinge and does not automatically close the gate.
Safetech specifies a maximum holding weight of 28kg for the hinge pair.
There is no closing-weight rating for the SHN-90L-1 because it does not contain a self-closing spring.
Safetech’s 28kg holding-weight rating is 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 capacity.
The SHN-90L-1 is the single-leg model. For a two-leg mounting configuration, select the Safetech SHN-90L.
Because the SHN-90L-1 does not provide self-closing action, it should not be selected where the application requires the gate to automatically return to the closed position unless an appropriate separate closing system is provided.
The gate must be supported during installation and should not be allowed to place its full weight on the hinges until both hinges have been correctly attached.
The gate and supporting posts must be structurally suitable for the loads imposed by the gate and hinge system.
