How to Install the Slimline 100 with Internal Gutter

Suitable for builders, awning contractors and confident DIY installers

Your awning arrives fully assembled and ready to fit. The integrated front gutter collects rainwater and directs it neatly from either end of the awning. Follow these steps to mount and seal your awning correctly.

Fixing type will depend on your wall — wall plugs & masonry bolts for brick and concrete, structural screws for timber framing behind cladding.
step01

Understanding your awning brackets

Your Slimline 100 with Internal Gutter arrives fully assembled and ready to fit, with the brackets already slid inside the side frames. Depending on the size of your awning you will have either a 2 bracket system (left and right) or a 3 bracket system (left, right and centre). When you unpack the awning you will be able to see which system you have.

The brackets — parts and function

Each bracket is a single welded unit made up of the wall plate and the arm.

The wall plate fixes directly to the wall. The arm is welded to the wall plate and projects outward, sliding inside the side frame of the awning.

The arm is slightly pitched downward — this creates the forward slope that directs water off the front of the awning.

Identifying left from right

Look at the wall plate. The two holes are always at the top — this tells you which way the bracket is oriented and ensures the arm pitches correctly for water runoff.

  • Left bracket — wall plate faces right toward the centre.
  • Right bracket — wall plate faces left toward the centre.
If you have a 3 bracket system you will also have a centre bracket. The wall plate extends on both sides of the arm — it looks like a T from above.
step02

How to measure for awning bracket spacing

Decide where the awning will be mounted. Measure the outside width of the 100×50mm aluminium box frame.

Do not include the angles or capping that secure the polycarbonate sheet.

This is your Frame Width.

Now subtract 10mm from the Frame Width. The result is your Bracket Width — the measurement between the outer edges of the two wall-mounted brackets.

Formula
Frame Width − 10mm = Bracket Width
e.g.  2000mm − 10mm = 1990mm
Write your Bracket Width down — you will use it to position your brackets in the next step. Always measure as close to the wall surface as possible — uneven walls may cause variations if measured further out.
step03

How to fix awning brackets to the wall

Fixing the left bracket to the wall first

Mount the left bracket first, making sure the wall plate faces toward the centre. Use a spirit level to confirm it is level and square to the wall.

If the wall surface is uneven, you may need to use packers to achieve a secure and even fit.

Fixing the right bracket to the wall

Measure from the outside edge of the left bracket to mark the correct position for the right bracket, based on your calculated Bracket Width.

Mount the right bracket, again checking that it is level, square, and aligned with the left bracket.

⚠ Take all measurements from the wall plate as close to the wall as possible.

If you have a 3 bracket system, fit the centre bracket after the left and right brackets are mounted.

Measure the outside width of the 100×50mm aluminium box frame.

Do not include the angles or capping that secure the polycarbonate sheet.

Measure from the outer edge of the left side frame to the centre of the centre frame. Subtract 5mm — this gives you the Centre Bracket Position.

Formula
Left frame outer edge to centre of frame − 5mm = Centre Bracket Position
e.g.  1500mm − 5mm = 1495mm

Mark that measurement on the wall from the outside edge of the left bracket. Mount the centre bracket at that point.

  • Mark the Centre Bracket Position on the wall.
  • Mount the centre bracket at that mark.
  • Measure from both the left and right side frames to confirm the position before final fixing.
A string line across the tops of the left and right brackets is a simple and reliable way to confirm the centre bracket is level with both.

How to fit your awning to the wall

Slide the awning over the brackets by inserting each bracket into the side frame channels.

The easiest way is to set one bracket into the frame first, then slide the next bracket into the frame.
step05

Setting the pitch for internal gutter drainage

The Slimline 100 with Internal Gutter works differently to the standard model. Rather than water running off the front edge, rainwater is collected inside the integrated front gutter and drains neatly from either end of the awning.

To achieve this, the awning must be set with a slight sideways pitch — angled toward the side you want the water to drain from.

  • To drain from the left end — raise the right side slightly so water flows left into the gutter outlet.
  • To drain from the right end — raise the left side slightly so water flows right into the gutter outlet.
  • To drain from both ends — set the awning dead level side to side using a spirit level across the front.
A spirit level across the front of the awning makes setting the pitch straightforward. ⚠ Do not pitch the Slimline 100 with Internal Gutter forward like the standard model — water must flow into the internal gutter, not off the front edge.
step06

Securing your awning to the brackets

Once the pitch is set and the awning is back against the wall, secure it by driving 2 Tek screws into each side frame — through the frame and into the bracket inside.

  • 2 Tek screws per side — 4 total.
  • Drive through the side frame into the bracket.
⚠ Drive screws through the side frame only — not through the top or bottom face of the frame.
step07

How to seal an awning to a brick wall

Finish the installation by applying a continuous bead of silicone along the joint between the rear of the awning and the wall surface.

Angle the nozzle so the silicone is forced into the gap between the awning and the wall rather than sitting on the surface. Silicone performs best when bonded between two surfaces under slight compression.

  • Use exterior-grade silicone.
  • Apply in one continuous bead with no gaps.
  • Tool smooth with a wet finger or silicone tool.
  • Allow to fully cure before exposure to rain.
✓ Installation complete. Your Slimline 100 with Internal Gutter is ready.

As a general rule, awnings under 3 metres will have 2 brackets and awnings over 3 metres will have 3 or more. This may vary depending on your wall structure and the wind rating requirements for your area — this is confirmed during the design stage before manufacture.
Each bracket has 3 fixing holes — 2 at the top and 1 at the bottom. Always orient the bracket with the 2 holes at the top, and ensure the wall plate faces inward toward the centre of the awning. Centre brackets have 6 holes but the same principle applies.
Yes, you can install onto a rendered wall as long as there is concrete or brickwork behind it. The Slimline 100 with Internal Gutter is specifically designed for this type of installation.
This depends on the type of timber framing behind the cladding. If you have an LVL header above a window, you may be able to mount the awning to that wall, provided there is sufficient structural timber to fix into. We also manufacture different awning models specifically designed to fix into timber studs. Give us a call and we will discuss which option is best suited to your situation.
You do not need to be a tradesperson. If you are handy and capable of using a drill and working with a spirit level, there should be no problems. The awning has been designed to be as straightforward as possible for a confident DIY installer.
On the Slimline 100 with Internal Gutter, water is collected inside the integrated front gutter and drains from either end of the awning. The drainage direction is set by adjusting the sideways pitch during installation — raise one side slightly to direct flow to the opposite end, or set it dead level to drain from both ends.
Use an exterior-grade silicone designed for outdoor use. Any silicone rated for sealing gutters and roofing will be suitable for sealing an awning.
Small gaps can be filled with silicone once the awning is fixed. In more severe cases, a flat angle may need to be fixed to the wall first. We recommend discussing this with us before installation so we can advise the best approach for your situation.
