The idea for Triline Quality Door Systems was born in 1996 when founder and home builder, Stuart Colledge, noticed that there was no easy way to obtain pocket sliding doors in Tasmania. After a few years of extensive product research, design and development, Triline launched its first cavity sliders in a leading hardware store in Hobart. Over the next eight years our output increased steadily and by 2004 we outgrew our facilities. 2005 saw us expand to a larger premises and, as a result, we have significantly increased our production output.
With more space and the passion to go further, we overhauled and re-designed our cavity pocket system. After much refinement and consultation with our customers, the Phoenix™ cavity slider was formed. We continue to grow and improve our product range to give our customers more options and avenues for creative exploration in internal sliding doors. We also seek ways to better construct our cavity sliding doors to ensure our customers have the latest in architectural design and material performance.
