Celebrating 30 years of Gainsborough Trilock

July 2025

This year Gainsborough proudly wishes Trilock a Happy 30^th Birthday!

When it comes to home security Gainsborough’s Trilock has been safeguarding Australian homes for over 30 years, with a knack for blending design with functionality.

Legacy

Gainsborough prides itself for being at the forefront of innovation, introducing Trilock 30 years ago with a dedication to merging security without sacrificing style. The Trilock system revolutionised the door hardware industry by offering a unique combination of lockset, deadbolt and passage function in one system.

Throughout the years Trilock has evolved not only to suit the needs of Australians but also the design trends that filtered through, offering a product to suit a variety of exterior styles.

The Traditional Knob set became a trusted staple in Australian households, offering a balance of practicality and reliability, as architectural trends evolved and homeowners sought more contemporary solution, Gainsborough responded reimagining the Trilock for a modern era.

The Trilock Omni Pull handle represents a bold departure from tradition designed to stunning statement pieces on grand entry ways with on trend finish proving that great design and functionality can stand the test of time.
