A CS CavitySlider is a functional and efficient alternative to conventional surface sliding or hinged doors.  Our cavity slider units enable a door to slide inside the wall leaving the floor and wall space on both sides clear and unobstructed.

The CS CavitySliders Ultimate HeavyDuty cavity sliding door system is designed to take thicker, higher, wider and heavier door leaves than any other products in our standard range.

The CS Ultimate HeavyDuty cavity slider is suitable for all types of applications however due to it's over-sized dimensions its mainly used in architecturally designed homes, commercial fitouts and industrial applications. 

 

CS Ultimate HeavyDuty
Design Features & Options:

• Removable jambs: If timber jambs are used they can be easily removed so if the door leaf ever bows, the vertical jambs can be scribed to match the door and refitted. This saves the costly replacement of the door, not to mention repainting and re-fitting hardware.
• Increased clearance: At 80mm the Ultimate's cavity width is wider than the 50mm of standard cavities. As a result the Ulitimate can accommodate doors up to 68mm thick however the ideal thickness door for this unit is 55mm.
• The Ultimate HeavyDuty is also capable of going extra high. The split jambs ed size these cavities have a unique 3 cell box section making them more rigid . They can be made even more rigid by inserting steel tubing into the three hollow cells of the section.
• Due to the over-sized nature of the Ultimate HeavyDuty, this unit's track may be sectioned and re-assembled on site where required.
• The wider back stud, bottom plate and track also add to a stronger frame.
• Architectural jamb options: square stopped and negative detail are available.
• Two options in jamb materials: either timber jambs that suit door thicknesses from 10mm through to 68mm, or powder coated aluminium with wool pile seals that suit door thicknesses from 66mm to 68mm only. 
• Fits into a 120mm stud wall.
• Can accommodate extra-high doors.
• More than one leaf may be joined to make one extra wide door.
• Extra Heavy-duty 4-wheel carriages supplied as standard.
• The wider appearance of these units fits in well with modern architectural trends.

  Note: The thicker the door used, the less you have available to scribe off the jambs.

• Available as single or bi-parting double units with or without the door fitted.
