Features of the Gainsborough Trilock series:

3 in 1 security: deadbolt, privacy and passage functions all locked into one set

Deadbolt security

Trilock houses a double cylinder deadbolt, with a sturdy 20mm throw, to keep possessions and valuables safe whilst the home is unoccupied.

Trilock’s deadbolt security means the door can be easily deadbolted from both sides.

Lockset with safety

Depressing the button on the inside of the door engages the Trilock privacy mode. This locks the door totally from the outside, however it is safe to exit without a key in an emergency by simply turning the knob or lever.

Passage set convenience

When Trilock is unlocked and unsnibbed, it operates as a standard passage set, allowing free access in or out of the home.

Single handed operation

The key operates all functions of the lock, allowing the external door to be opened without rotating the knob or lever. This conveniently leaves a spare hand free for carrying parcels and the like.

Euro cylinder

The solid brass, 5 pin Euro profile cylinder is securely housed within the Trilock body.

The Trilock series marks an amazing advance in the design and manufacture of door security. It offers the best of all worlds with its unique combination of "3 in 1 security".

Durable decorative finishes
The Trilock series is available in a choice of four durable, tarnish resistant finishes that carry a limited 5 year guarantee against tarnishing under normal use.

This ensures that the best in security can also live in harmony with the home’s decor. Gainsborough’s revolutionary “Durabrass®” achieves the charm and distinction of brass without the problems of tarnishing. The Trilock series is also covered by a 10 year limited mechanical guarantee.

Easy installation

Each Trilock pack includes easy to follow, do-it-yourself instructions which allow any home handyperson to install Trilock.

When replacing worn keylocks, Trilock fits readily into the existing 54mm (2 1/8'') cross bore hole. All the necessary tools required for installation may be found listed on the retail packaging.

Forced entry resistance

Trilock’s reinforced jamb striker plate has successfully exceeded the maximum Australian Standard “Security Strength Impact Test-S3”, making Trilock jemmy resistant to intruders.

Keying for convenience

Trilock can be keyed alike to other Gainsborough residential lock cylinders for one-key convenience.

Made in Australia

Trilock, recipient of an Australian Design Mark for good design, has been developed and manufactured in Australia by Gainsborough and is protected by international patents.

Trilock dummy sets for double doors

Non-operational Trilock dummy sets are available in both knob and lever versions to provide a matching set on double doors.

Easily handed

Trilock with lever features an innovative design characteristic which allows levers to be easily rotated for use on left or right handed doors.
