How to Install the
Slimline 50 Under Eave

Suitable for builders, awning contractors and confident DIY installers

This guide covers everything you need to install your under eave awning Sydney correctly. The Slimline 50 under eave awning mounts to the wall below the eave — the arm travels under the overhang to the fascia line where the panel sits. Three fixing points: wall bracket to wall, rear rail to fascia, front rail to arm tongue. For NSW installation requirements visit NSW Fair Trading.

Fixing type depends on your wall — structural screws into timber studs for cladded walls, masonry bolts for brick or concrete. Never fix into cladding alone.
step01

Understanding your Slimline 50 under eave awning system

Slimline 50 under eave awning Sydney — three fixing points showing wall bracket, fascia fixing and arm tongue
Three fixing points — wall bracket fixed to wall, rear rail fixed to fascia, front rail fixed to arm tongue

The Slimline 50 Under Eave uses a wall bracket and arm system. The wall bracket fixes to the wall below the eave. The arm then travels horizontally under the eave overhang and projects outward to the fascia line — this is where the awning panel begins.

There are three fixing points as shown in the diagram:

  • Fixed to wall — the wall bracket screws to the wall through the timber studs behind the cladding.
  • Fixed to fascia — the rear rail of the awning panel screws to the fascia board at the front of the eave.
  • Fixed awning to arm — the front rail of the awning panel seats onto the tongue at the front of the arm and is secured with a Tek screw.
Push the arm hard up against the underside of the eave before fixing the wall bracket. This ensures the arm sits at the right height so the awning panel aligns flush with the fascia.
step02

Under eave awning bracket and arm parts explained

The wall bracket

The wall bracket is the component that fixes to the wall. It has a vertical plate with 3 fixing holes — these are where the structural screws go through the cladding and into the timber stud behind it.

At the top of the bracket is a U-channel — this is where the rear end of the arm slots in and is locked with 4 Tek screws, 2 on each side of the channel.

Assemble the arm into the bracket on the ground before lifting to the wall — much easier than working at height.

The arm

The arm is a 50×50mm aluminium section. The rear end slots into the U-channel of the wall bracket. The front end has a tongue — this is the tab that seats up into the front rail of the awning panel and is secured with a Tek screw.

  • Rear end — into the wall bracket U-channel, locked with 4 Tek screws.
  • Front end — tongue seats into the front 50×50 rail of the awning panel.
The tongue at the front end is your orientation reference — it tells you which way the arm faces before you assemble anything.

How to fix your under eave awning brackets to the wall

First assemble the arm into the wall bracket on the ground:

  • Slide the rear end of the arm into the U-channel of the wall bracket.
  • Lock it firmly by driving 4 Tek screws — 2 on each side of the channel.

Fixing the assembled bracket to the wall

With the arm locked into the bracket, fix the assembled unit to the wall:

  • Hold the assembled bracket and arm against the wall. Push the arm hard up against the underside of the eave before drilling anything.
  • Mark the 3 fixing hole positions through the wall bracket onto the wall.
  • Drill and plug the wall as appropriate for your wall type.
  • Fix the bracket to the wall with the appropriate screws — structural screws into studs for cladded walls, masonry bolts for brick or concrete.
  • Check level before tightening fully.

Wall fixing types and final checks

⚠ The type of fixing screw depends on your wall type. Structural screws for timber studs behind cladding, masonry bolts for brick or concrete. Never fix into cladding alone. Fix all brackets to the wall and recheck level across all arms before moving on to fitting the awning panel.
step04

How to fit the awning panel onto the arms

With all brackets and arms fixed to the wall, lift the awning panel into position on top of the arms.

  • Lower the awning panel down so the front 50×50 rail seats onto the tongue at the front of each arm.
  • The rear rail should sit flat against the fascia board at the back.
  • Make sure the front rail is fully and evenly seated on every arm tongue before driving any screws.
The awning panel should sit flat and level with no rocking. If it is not sitting evenly, check that all arms are at exactly the same height before proceeding.
step05

How to fix the awning panel to the fascia and arms

Mark through the pre-drilled holes in the rear rail and fix firmly to the fascia

Fix the awning panel in place from both ends:

  • Rear rail to fascia — the rear rail has pre-drilled holes. Mark through these holes onto the fascia, drill and plug if needed, then fix the rear rail firmly to the fascia board.
  • Front rail to arm tongue — drive a Tek screw down through the front rail into the tongue on each arm to lock the front of the panel in place.
Fix the rear rail to the fascia first — this holds the awning steady while you drive the Tek screws into the arm tongues at the front.
step06

How to seal the awning

Apply a continuous bead of exterior-grade silicone along the joint between the rear rail and the fascia, and along any joint between the side frames and the wall where water could enter.

  • Apply in one continuous bead — no gaps.
  • Tool smooth with a wet finger or silicone tool.
  • Allow to fully cure before exposure to rain.
✓ Installation complete. Your Slimline 50 Under Eave is ready.

Yes. This under eave awning Sydney is specifically designed to work with an eave and fascia. The arm travels under the eave and the rear rail of the awning fixes to the fascia board. If your home does not have an eave at the required location a standard Slimline 50 or Slimline 100 would be more suitable.
The height of the arm against the eave determines how the awning panel sits relative to the fascia. If the arm is fixed even slightly low the rear rail will not sit flush against the fascia and there will be a gap. Pushing the arm firmly up before fixing ensures everything aligns correctly.
Yes. On a cladded wall the wall bracket must be fixed into the timber studs behind the cladding using structural screws. Use a stud finder to locate and mark studs before drilling. Never fix into cladding alone.
Yes. On a brick or masonry wall use masonry bolts of the appropriate size through the wall bracket fixing holes. The installation process is otherwise identical.
The number of arms depends on the width of the awning. Wider awnings will require a centre arm in addition to the two end arms. This is confirmed during the design stage before manufacture — every awning is custom made to suit your specific opening.

You do not need to be a tradesperson to install your under eave awning. If you are comfortable using a drill, working at height on a ladder, and using a spirit level there should be no problems.

Assembling the arms on the ground before lifting makes the job much more manageable. Two people is recommended for lifting the awning panel into position.

Use an exterior-grade silicone designed for outdoor use. Any silicone rated for sealing gutters and roofing will be suitable.
Small gaps between the rear rail and the fascia can be filled with silicone. For larger gaps or uneven fascias, packers behind the wall brackets can bring the arms out to the correct level. We recommend discussing any unusual eave or fascia conditions with us before ordering.
