Our units are unique in the way we construct them and depending on the brand you compare, there are different levels of quality and standards of finish. All of our units are top quality - they need to be because they finish up inside your wall! All of our cavity sliders are made in New Zealand, BRANZ appraised and covered by a written 10 year warranty.
Our cavity frames are manufactured from high quality extruded aluminium and high grade renewable timber resources.
We recommend 35-38mm thick doors for most of our systems. Multiple OvertakingDoors units are best used with 38mm thick doors. If your door is 40mm plus in thickness just ask for our Ultimate cavity slider system which can accommodate doors up to 88mm thick!
Generally speaking we can supply a cavity slider system to suit any door size. For massive doors that are over 4m high and 5m wide, please consult us - we have solutions available!
A pair of single (M6) carriages will take 120kg. If your door happens to be heavier we have heavy-duty carriages available to suit doors up to 240kg (M8) or if your door is heavier still, step up to our M10 (500kg) carriage series.

Yes, CS Cavity Sliders products can be made to comply with NZS 4121:2001. For compliance with NZS 4121:2001 standards, the centre of your handle should be positioned between 900mm and 1200mm (1000mm optimal) above the finished floor level. The door must be at least 910mm wide to allow a minimum clear walk-through of 760mm. There must be 45mm of clear space from the edge of the pull handle to the nearest door jamb when the door is both fully open and completely closed. A flat closing jamb is recommended. The supplied ‘Down to Lock’ label must be positioned as close as possible to the handle. Consult local standards for guidelines relating to the specific project.
We manufacture our door systems at our factories in Auckland and Christchurch. We also have stock holding capacity in our Tauranga branch. Click here for a list of distributors by region.
If required, we can organise delivery nationwide. Our commitment to high quality means we want your product to arrive at your delivery address in the same condition as when it left our factory. For this reason, we are very particular about who we allow to transport our product and this means using Furniture Transporters to send our goods to you.
Your order may take a bit longer to arrive than with standard freight carriers, but should arrive in excellent condition.
If you require urgent or overnight delivery and are happy to take the risk, you will need to organise your own freight.
Contact us to request a credit application form.
Frames to suit standard-sized doors are kept ex stock and are available for next-day delivery and in some cases, same-day collection.
Custom units take approx. 7 - 14 business days to manufacture from point of order confirmation and supply of any customer-supplied components. If your unit contains glass, non-standard doors, or powder-coated components, these can all affect the lead time. Contact us for up-to-date information on current lead times.
A Track Stop is needed when no physical stops are present, i.e., your door does not come to rest at a closing jamb or wall stud.
Example: A pair of bi-parting doors or a surface sliding track.
A CS SofStop mechanism is designed to slow down the door. It must be paired with a physical stop such as a "Track Stop" or closing jamb to ensure the mechanism does not break.
To use the CS SofStop in your project, your door must meet minimum door width requirements. Please review the table on the CS SofStop product page to confirm that your door is compatible.
1. Stand with your back against the door’s closing jamb
2. Look directly into the door’s cavity
3. Determine which side you’d like your snib (Privacy Function) or key on.
Example:
The homeowner would like to add a lock to this bathroom. Upon
positioning themselves and looking into the cavity, the homeowner’s
RIGHT hand is inside the bathroom. Therefore, the door’s handing would be: Right Hand (RH) Snib/Left Hand (LH) Emergency
There are no regulatory issues to consider when installing a cavity slider in your bathroom, en suite, laundry or other wet area, but there are some practical common sense things to consider:
H3 treated jambs nogs and skirting blocks (all options available from CS).
Consider where any plumbing needs to run, as it cannot run in the pocket - consider a false wall beside the pocket for this.
If tiling, then we recommend lining the pocket with 9mm masonry board first before tiling to give the wall rigidity. Tiling your pocket or running a false wall beside your cavity pocket will require a non-standard width jamb on one side which we can easily provide for you.

We are a manufacturer only. Our products can be installed by any competent builder. Depending on the job, we may be able to recommend a subcontractor or put you in touch with a builder to do the job.
Pre-finished items should be cleaned regularly (at least once every 6 months in interior applications and more often in industrial or exterior environments) with a dilute solution of mild, neutral liquid detergent, e.g., dish washing detergent, warm water (40˚C), and a soft, lint free cloth or brush.
Do not use abrasive cleaning tools such as steel wool, hard brushes, abrasive scourers, etc., as these may damage the coating surface and change the colour or gloss levels of the finish. Rinse suds off thoroughly with fresh water and dry with a clean cloth.
It is vital that any other chemicals such as petrol, strong alkalines or acids are NOT used on any prefinished surface. Pre-finished items that are maintained regularly should retain their good looks. They will not crack, chip or peel as with conventional finishes.

If care is taken during the installation process, then in most cases there is no need for further maintenance.
The most common time for dust to accumulate is during building works. For this reason, we recommend taping up the track after installing the cavity slider, but before applying wall linings. This helps to prevent dust, debris or paint build-up during construction.
After installation, regular maintenance is not required. However, if you notice a change in the way the door runs or sounds, a quick inspection of the carriages and aluminium track running surface is recommended. The track can be cleaned with compressed air or wiped down with a soft rag.
CS cavity slider tracks feature a convex wheel channel, which causes less friction and dust build up. This also makes the system quieter and smoother running.
