Cavity units

Three systems, one upgraded range.

The disappearing act made smoother

We’ve reengineered our Cavity Sliding range with new hardware, a jump‑resistant soft closer, and a quieter aluminium track system so the disappearing act is silently smooth.

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.

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

Note: Slimline 5000, Platinum 7000 and Platinum 9000 are currently available in NSW only.

Soft close with jump resistance

Re‑engineered soft closer catches earlier, guides smoother, and reduces bounce.

Quieter aluminium track

Self‑balancing rollers on aluminium track for less noise and smoother operation.

Customise with add-ons

Choose from a range of options to make install or operation even easier.

Made in Australia

Designed and built locally for Australian conditions, lead times, and support.
