Cavity units

Sometimes, styling a space also means making the most of that space—it’s a common challenge for ensuites, walk-in wardrobes, bathrooms, and laundries.

In these cases, sliding cavity door systems are the perfect blend of style and efficiency. They can complement a wide range of aesthetics before sliding conveniently and discreetly into the unit housed within the wall, saving on the room that would otherwise be taken up by a hinged door.

When selecting your Cavity Unit, it is important to select the right Cavity Unit for the size and weight of your doors: whether it is for a single door or double door slider, and whether you would like a soft closer mechanism.

We offer both steel cavity units (called the Platinum range) and timber (Slimline), which are compatible with our extensive range of interior door designs. Platinum cavity units provide added strength. They’re ideal for heavy floor-to-ceiling doors, tiled walls, and wet areas where moisture can damage timber units.

Platinum 4000 Steel Cavity Units

Corinthian Doors Platinum 4000 Cavity Units can carry wider and heavier doors. They are suitable for homes and commercial applications and are available with an optional Soft Closer to prevent slamming.

Features of the Platinum 4000 range include:

Steel construction can carry heavier and wider doors – up to 65kg single door and 45kg per door for double sliding door applications.
Steel construction is resistant to warping, bowing, and moisture damage.
A jump proof twin roller track with dual axle ball bearing for smooth running.
Suitable for tiled wall applications.
Press-release option for easy door retrieval from the cavity pocket in flush jamb configuration.

The Platinum 4000 Cavity Unit range can also come with an optional Soft Closer Kit. When selecting your Soft Closer Kit please order based on the weight of your door.

Soft Closer Kit – for doors weighing 10kg to 19kg
Soft Closer Kit – for doors weighing 20kg to 39kg
Soft Closer Kit – for doors weighing 40kg to 65kg

Ask your builder or hardware retailer to include a Soft Closer Kit when ordering a Platinum 4000 Cavity Unit.
