Shadowline Masonry Picture Rail

How is the Shadowline Masonry Picture Rail installed?

1. Fix the rail to the masonry wall during the build or renovation phase, before final ceiling finishing.
2. Install after render/wall finish, before installing the suspended ceiling structure. (It can also be used where wall linings go in before the ceiling structure – for example fire-rated construction.)
3. Use the correct fixing density: 9 screws per 2.5 m rail (roughly every 25-30 cm). Choose plugs and screws to suit your wall substrate.
4. The rail is not pre-drilled, so drill where you need solid fixing points and keep screw heads flush.
5. Slide the plasterboard ceiling sheet into the rail flange and finish the junction with setting compound as part of the normal ceiling build.

Finishing tips

• Insert the ceiling lining sheet fully into the capture flange.
• Fix the plasterboard ceiling sheet to the shadowline rail every 600mm to prevent any sheet movement.
• Use adhesive paper tape at the junction to improve adhesion and crack resistance.
• Acrylic setting compounds are recommended to bond well to the rail’s primed finish.

Which hanging wires and hooks work with this rail?

Shadowline Masonry uses Twister hanging wires, which twist into the rail slot at any point along the track. You can then slide them left or right to fine-tune placement.

For the hanging line itself, choose:

• perlon (clear nylon) for a more invisible look
• steel wire for a cleaner, more architectural finish

Pair them with hooks and hanging wires based on the pictures’ weight. Most artworks sit comfortably within the system ratings – if you’re hanging something unusually heavy, we can help you choose the right combination.

What is the difference between Shadowline Masonry and Shadowline Drywall rails?

The difference is where the rail fixes structurally. Both still sit in the wall/ceiling junction and create the same concealed shadowline effect.

Shadowline Drywall is a ceiling-fixed built-in rail. It fixes to the ceiling structure before plasterboard goes up, then disappears into the shadowline detail.

Shadowline Masonry is a wall-fixed built-in rail. It fixes to the wall structure, including masonry, concrete, timber or steel framing, and also disappears into the wall/ceiling shadowline.

Both are built-in concealed picture hanging systems. Once installed, you don’t see a surface-mounted rail – only the shadowline opening where the hanging wires insert.

Why choose Shadowline over wall-attached rails?

Completely invisible hardware, pristine walls, no repaint when you move or rotate art – installed by Australia’s best builders for upmarket residential, commercial, healthcare and aged care projects.
