Do CS Cavity Sliders products comply with Australian Standard® AS1428.1.2021 Design for access and mobility?

Our cavity and sliding doors specified without the CS SofStop comply as the operating force is less than 20 N. The clear opening of the width of the doorway must be 850mm. In the case of bi-parting double doors, the clear opening applies to the active leaf. Refer to AS1428.1.2021.10.3 for guidelines to observe proper clearance for circulation space.

Our CL400 Magnetic DDA is designed to comply with Australian Standard® AS1428.1.2021

For proper installation:

Door controls that need to be grasped or turned must be 900-1100mm high.

Controls that need to be grasped, turned, pushed or pulled to operate a door must be 900-1100mm high and minimum 500mm from an internal corner (except within lift cars).

How do I open an account with your company?

What is a "Track Stop"?

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.

What is a "CS SofStop"?

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.

How Do I Choose the Handing of My Hardware?

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

How to Choose Your Handing for Cavity and Sliding Door Hardware

Installation & Maintenance

Are there compliance or regulation issues about cavity sliders and bathrooms?

CS Cavity Sliders can be configured with a full ply panel instead of nogs on one or both sides of the Cavity Frame, ideal for additional fixing like grab or towel rails in bathrooms and even some cabinetry. Cavity Sliders frames meet AS 1720.1, 2010 requirements, supporting up to 50kg/m² as tested. Follow the manufacturer’s instructions for installation compliance.

Do you install?

We are a manufacturer only. Our products can be installed by any competent builder. All units are supplied with complete installation instructions.

How do I care for pre-finished aluminium products?

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.

For more information, please refer to the data sheet for Pre-finished Aluminium products here.

How do I remove the door from my cavity slider?

Remove the Head Jamb: Choose the best side to remove the door from and remove the head jamb on that side by first removing any architraves. Hint: Make a thin knife cut where any paint joins two components so as not to tear existing paint work. Remove the wooden plugs covering the screw heads. Remove the screws holding the head jamb in place, then gently tap jamb to remove.
Remove door from track: Use the extended part of the spanner to press down the plunger pin that protrudes up from the mounting plate. Once this plunger is fully depressed, slide the spanner sideways towards the plunger pin. The whole carriage (including the hanger pin) will now disengage from the mounting plate.

How do I clean a cavity slider track?

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.
