Start by carefully planning your railings to scale; this will limit cutting and wastage and
you to be accurate when ordering the materials you need
When planning your design, make sure the height of the top railing is at least 900mm from
of the deck, and that deck posts aren’t spaced more than 1800mm apart
We are adding ‘modern’ decking spindles to our raised deck. Bear in mind when using these
that the maximum deck height they can be used on is 600mm, so if your deck is any higher,
require a different railing design
Do it right
To extend the life of your railings, add two coats of preservative to any cut ends or
In order to ensure your spindles are evenly spaced, create an 81mm spacer using an offcut of
You can then lay this horizontally to mark the 81mm spacing between spindles and vertically
on the railing where each spindle will be placed
It is possible to assemble your deck railings on your own, but it is much easier with a
hands, so ask a friend if they can help out
Firmly secure the timber and take care when sawing, drilling and hammering in the nails
When drilling it’s best to wear safety goggles
Wear protective gloves when sawing, handling the deck posts or applying wood preserver
Wear a dust mask, ear protectors and safety goggles when using a jigsaw or circular saw
Always follow manufacturer’s instructions for drying and safety when using wood preserver
Offcuts of treated timber should never be burnt, but need to be disposed of safely – your
recycling centre should be able to advise
Once the railings are in place, add a coat of decking stain to further protect and enhance
natural beauty of the timber
Dirt can be removed from the railings with regular brushing or by using a specific deck
fluid, but be sure to follow the instructions on the packaging
We do not advise using a pressure washer to clean decks and deck railings as they can damage
preservative layer on the surface of the wood
Preparing the deck posts:
Notch out the deck posts 120mm x 20mm up from the bottom. Or, to make this part of the
much easier and faster, you can buy these pre-notched. If you need to extend your notch
then do this using a handsaw or circular saw.
Ask someone to hold the deck post in position whilst you mark the location of two evenly
pilot holes on the post.
Secure the post in your bench and drill the pilot holes using an 8mm wood drill bit.
To fix the deck posts to the bearer, hang washers on the end of a 130mm exterior coach screw,
then tighten the screws with a socket set.
Use a tape measure to make sure deck posts are evenly spaced, with a maximum distance of
If you want the post to be flush to the decking then you will need to notch it into the
Start by marking out where the post will be onto the deck and the fascia.
Remove the fascia and use a hand saw to saw off the section you’ve marked out.
Use a jigsaw to remove the top section.
Put the post into position and check that it is flush to the decking. Then, secure the post
before and reattach the fascia.
Assembling the railing
Measure the gap between the posts, so the top and bottom rails can be cut to fit between
To make sure spindles are placed evenly, measure and cut a piece of spindle to 81mm and use
as a marker.
Measure 81mm from the end of the rail and use a try square to mark an accurate line. This
marks where the first spindle will be placed.
When you are marking the bottom railings, mark the centre of each spindle, as this is where
pilot holes will be drilled.
Turn the 81mm section on its side, and continue to mark along the length of railing. You may
to adjust these measurements slightly to fit the length of your handrail. However, make sure
spacings are equal and do not exceed 82mm before fixing.
For the bottom rail, repeat the above but with the addition of drilling a 3mm pilot hole
Attach the spindles to the bottom rail using 76mm deck screws. You may need someone to hold
in place for you whilst you screw.
To attach the top rail to the spindle, use a 64mm galvanized finish nail, but take care not
damage the wood whilst hammering. Alternatively, you could use a nail punch to finish the
Fitting the railing
Place the long side of the L brackets centrally into the fillet slot, on the underside of the
bottom rail. Check the L brackets do not stick out past the end of the rail, then fix the
bracket to the bottom rail using the two 25mm screws that are supplied in the kit.
Mark on your deck post where you want the top railing to be, making sure it’s at least 900mm
Centrally place the short side of the L bracket onto the mark and fix the bracket to each
post using two 25mm screws.
Place the railing assembly on the fixed post L brackets and secure to the underside of the
rail using two 25mm screws.
Centrally locate the bottom rail on the deck post, before fixing the bottom rail L bracket
two 25mm screws.
On each side of the top and bottom rails, measure 25mm from the end of the rail and mark.
Drill a countersunk 3mm pilot hole approximately 30 degrees through the rails and into the
Finally, skew two 50mm screws into each rail to secure to the post.
