Cavity Sliders - What is a Cavity Slider (Pocket Door)?

Choosing the right Cavity Slider (Pocket Door) for your project may be more important than you think! Most common complaints about Cavity Sliders are due to inferior quality products or issues with installation.

The Basics - What is a Cavity Slider? 

The term ‘cavity slider’ refers to the cavity pocket (including the track and carriages) installed within wall framing that allows a door to slide inside the wall. A door and handle is also required - you can supply these yourself or order them through us for a complete package.

So, why choose Cavity Sliders? For peace of mind. Our patented design has been tested and improved upon since 1986. Our Cavity Sliders have a BRANZ appraisal and is covered by a written 10-year warranty. Individually engineered components are built to last and sourced from local and sustainable resources wherever possible.

Choosing your Cavity Slider

First, you’ll need to decide the size of your Cavity Slider.

The CS Cavity Slider Pocket Frame comes in 3 standard sizes: 3'0 x 6'8", 3'0 x 8'0, and 4'0 x 8'0 (which can be cut down to size on site if necessary) and can accommodate 1-3/8" and 1-3/4" doors. 

Next, you'll choose your carriage pack.

Your carriage pack is the set of "rollers" (also known as "trolleys") that you will attach to your door, enabling it to roll into and out of the pocket. If you would like your door to include a soft close and/or soft open, you can choose to utilize our SofStop mechanism. Note: In order to use the SofStop, your door must meet minimum widths to accommodate it. Please see below.


For a bi-parting pair of doors, stops will need to be added to your carriage packs.

Choosing Your Pocket Door and Door Hardware

The Cavity Slider accommodates any 1-3/8" or 1-3/4" doors.

Door handles are that added touch of detail on your pocket door. There are many options out there, but if you are looking for functional, good looking, high-quality NZ made sliding door hardware, select from the CaviLock range.
