Expandable barriers are designed to help control pedestrian access and temporarily restrict entrances, workshops, roller doors and other areas. They are not designed to provide the same level of protection as a steel security gate.

Expandable Barrier Components

Your barrier includes:

• Expandable barrier panel made from aluminium tubing
• 1 × 200mm latching L bracket
• 3 × 130mm fixing L brackets
• 2 × barrier brackets
• 1 × Anti-Luce wall fastener, also known as a drop latch or trailer latch
• Swivel castor with foot lock

The 200mm latching L bracket may be supplied in a zinc-coated finish instead of powder-coated yellow, depending on stock availability.

Note: Screws and fixings are not included. An 8mm Dynabolt is recommended for fixing into concrete, while a suitable hex-head wood screw is recommended for fixing into a timber frame. Always confirm that the fixing type and length are appropriate for the mounting surface.

Step 1: Measure the Entrance

Before selecting or installing your expandable barrier, measure the area you want to cover.

Measure:

• The full width of the entrance
• The required barrier height

Measure the width from the intended fixing point on one side to the locking point on the opposite side.

---

Step 2: Check the Distance from the Door or Roller Door

Position the expandable barrier far enough away from the door or roller door so that both systems can operate without touching.

Before drilling:

1. Open and close the door or roller door.
2. Make sure the roller door can lower fully without resting on the barrier.

If the roller door comes down onto the barrier, it may damage the barrier or place unnecessary strain on the roller-door motor.

The barrier can often be installed behind the roller-door track, provided there is a suitable timber stud, concrete surface or other strong fixing point. The transcript also stresses checking for obstacles such as a nearby power box before deciding the final fixing position.

Step 3: Choose the Fixing Direction

The barrier may be installed using either a face-fix or sill-fix arrangement, depending on the opening and available mounting surface.

Face Fix

The brackets are fixed onto the front face of the wall, frame or supporting structure.

Face fixing may be suitable when:

• There is a strong flat surface beside the opening
• The barrier needs to sit in front of the opening
• There is not enough suitable space inside the entrance

Sill Fix

The brackets are fixed into the side or rear surface of the opening.

Sill fixing may be suitable when:

• There is a timber stud behind the frame
• There is a concrete side wall
• The barrier can sit further back from the entrance
• A cleaner and straighter installation line is available

Choose the fixing direction that provides the strongest practical fixing point while keeping the barrier clear of the door, roller-door track and other obstacles.

Step 4: Position the Fixing Brackets

The three 130mm fixing L brackets secure the fixed side of the expandable barrier to the mounting surface.

Position the brackets along the side of the barrier.

Important positioning requirements

• Leave a small gap between each fixing L bracket and the barrier bracket.
• Do not position the fixing bracket so high that it interferes with the barrier slides.
• The brackets should generally remain below the next rivet line.
• The barrier slides must be able to move downward when the barrier extends.
  

A small clearance between the fixing bracket and barrier bracket is important. If they press against each other, the barrier may not extend or retract smoothly.

Where an obstacle prevents the preferred position, the bracket can be moved slightly upward, but it should not be positioned above the recommended rivet area.

Step 5: Mark and Drill the Fixed Side

Once the position has been confirmed:

1. Hold the barrier in its intended position.
2. Check that it is straight and vertically aligned.
3. Mark the fixing holes through the L brackets.
4. Confirm that the marks align with solid timber, concrete or another suitable structural surface.
5. Drill the required holes.
6. Fix the brackets securely.

For concrete, use suitable 8mm Dynabolts where appropriate.

For timber framing, use suitable hex-head wood screws of the correct length and diameter.

Do not rely on thin wall lining, decorative trim or unsupported material as the main fixing point.

Step 6: Test the Barrier Alignment

After securing the fixed side, slowly extend the barrier across the entrance.

Check that:

• The barrier travels in a straight line
• The castor rolls smoothly
• The barrier does not twist
• The slides can move downward freely
• The opposite locking side reaches the intended position
• The barrier remains clear of the door or roller door

Do not permanently install the locking side until the barrier has been fully extended and its final position confirmed.

How to Extend and Retract the Barrier

Use the 200mm latching L bracket as the operating handle.

To extend the barrier

1. Release the swivel castor foot lock.
2. Hold the latching L bracket.
3. Pull the barrier slowly across the opening.
4. Keep the barrier aligned while it expands.
5. Position the latching bracket over the Anti-Luce fastener.
6. Drop the bracket down over the fastener.

To retract the barrier

1. Remove any padlock.
2. Lift the latching bracket off the Anti-Luce fastener.
3. Fold or hinge the latching bracket out of the way.
4. Push the barrier slowly back toward the fixed side.
5. Apply the castor foot lock when required.

Do not allow the latching bracket to swing back into the barrier while it is retracting. This may cause it to catch and could bend the castor-side post. The transcript recommends using the bracket as the handle and folding it safely out of the way during operation.

Step 7: Install the Anti-Luce Wall Fastener

The Anti-Luce wall fastener is also commonly called a:

• Drop latch
• Trailer latch
• Anti-Luce fastener

Install it on the opposite side of the opening after the barrier has been fully extended and aligned.

Installation position

1. Extend the barrier to the required width.
2. Hold the latching L bracket against the opposite fixing surface.
3. Position the Anti-Luce fastener between the barrier slides.
4. Aim for a central position where practical.
5. Leave enough clearance between the latch, bracket and moving slides.
6. Mark and drill the fixing holes.
7. Secure the fastener to a suitable structural surface.

The latching L bracket should fit over the Anti-Luce fastener and drop downward into the secured position.

Lock the Barrier

A padlock may be fitted through the lower section of the Anti-Luce fastener.

Use a padlock with a shackle no greater than 8mm in diameter.

For the strongest locking position:

1. Drop the latching bracket completely over the Anti-Luce fastener.
2. Insert the padlock through the lower locking hole.
3. Confirm that the bracket cannot be lifted upward.
4. Lock the padlock and test the barrier.

Installing the padlock too high may allow the bracket to lift slightly and create unnecessary movement. The lower locking position is recommended because it prevents the latch from being raised without removing the padlock.

Step 8: Adjust the Swivel Castor

The swivel castor supports the moving side of the barrier.

Check that:

• The castor remains in contact with the floor
• It rolls smoothly across the full opening
• It does not carry excessive weight
• The barrier remains upright
• The foot lock operates correctly

Use the foot lock to help hold the barrier in position when required.

Uneven floors may affect how smoothly the barrier moves. Test the full travel distance before completing the installation.

Expandable Barriers vs Security Gates

A Yellow Expandable Barrier is primarily an access-control and pedestrian-management barrier.

It can help:

• Restrict entry into a work area
• Control pedestrian movement
• Close off a roller-door entrance
• Create a visible boundary
• Temporarily restrict access
• Separate customers from operational areas

However, it is not designed to provide the same protection as a steel security gate.

The open diamond pattern is relatively large, and the aluminium barrier remains flexible. A person may still be able to reach through, move the barrier or access items positioned too close behind it.

For this reason:

• Do not install it directly in front of a window that requires burglary protection.
• Keep valuable items away from the barrier.
• Do not treat it as a substitute for a security grille.
• Do not rely on it as the only security measure for a high-risk entrance.

For stronger protection, consider a steel security gate such as Saftidor, which has narrower diamond openings and a more rigid steel construction. The transcript clearly distinguishes the expandable barrier as an access-control product rather than a full security gate.

Final Installation Check

Before using the barrier, confirm that:

• The opening was measured correctly
• All brackets are fixed into suitable structural material
• The barrier is straight
• The barrier does not interfere with the door or roller door
• All moving slides have sufficient clearance
• The castor moves smoothly
• The latching bracket operates correctly
• The Anti-Luce fastener is securely installed
• The padlock fits through the lower locking point
• The barrier extends and retracts without catching

Stop using the barrier if any bracket, rivet, castor or fixing becomes loose or damaged.
