QIII is a residential tower development in the heart of the East Perth Re-development precinct, bounded by Hay St and Adelaide Terrace, adjacent to the WACA.

CS Cavity Sliders supplied over 180 cavity pockets to the project through Diploma Construction. These pockets were custom made to suit on site detail matching a critical underside of head measurement. All units were finished with a Shadowline detail on the jambs made easier by the incorporation and additional strength provided by the CS 3-cell split jamb. The penthouse units incorporated soft closing cavity sliders – the CS SofStop.

CS dealt with site Foreman Raj Dungar on the project liaising in terms of turnaround times to meet the project schedule and ensuring all measurements were accurate and understood. CS flew to Perth to meet with Diploma to finalise product design and to demonstrate the ease of installation of product.
