Technology first. Product second.

The mechanism
makes the difference.

A clampable hinge, an adjustable knuckle and a concealed pivot solve different interface problems. VIALLA adds the separate decisions of how the door is operated and locked.

Post-installation correction

Three ways to retain alignment.

Start with the fixing interface and required movement. Then check the load configuration and complete door geometry.

Trinity 4414

The adjustment lives
inside the hinge.

Trinity suits conventional aluminium systems without a clampable C-groove. Its body and knuckle contain the adjustment mechanism; fixing remains a direct screw connection.

Lift-off capability is retained, provided the required clearance above the door is available.

Aluminium Euro Hinge 4670

A system hinge.
A defined profile interface.

Base and backing plates engage the C-groove. Height, horizontal and compression correction are provided through the clamp-mounted architecture.

Available adjustment can be affected by the space between the customer extrusions. Compatibility is reviewed system by system.

Pivotron 4131

Conceal the pivot.
Keep the correction.

The current 0 mm offset set provides height and width adjustment. Its concealed arrangement must be reviewed against the door offset, fixing envelope and opening geometry.

VIALLA / Two different user actions

The lever operates the latch.
The button operates the snib.

Do not confuse the two. Selected 5273 furniture uses a push-button snib instead of a small rotating control. 5278 adds a returned lever end for a different grip experience.

5271 / Push-button furniture

5271 conventional lever with a push-button snib.

Less pinch-and-turn at the snib.

The push-button concept is intended to reduce fine gripping and twisting when snibbing the door from inside. It is specific to the 5273 platform, not 5173.

5278 / Hook-return furniture

Retained contact at the lever.

The return is designed to help a user with limited grip or hand function maintain contact during latch operation. It is not a claim of automatic opening.

Accessibility design, assessed in context

The 5278 was developed around the accessibility principles of AS 1428.1: supporting operation where a conventional grip is difficult or not possible. This is a design reference, not certification of the handle or a complete door installation.

Standards Australia: AS 1428.1:2021

5273 / Lock platform

One platform. Several sets.

5274, 5275, 5276 and 5277 combine the 5273 lock with different furniture. SS304 latch/bolt is specified on 5273-071 and 5273-072; this is not a standalone fire-rating claim.

5189 / Multipoint hardware

Remote points. Separate kit.

The 5189 three-rod kit is supplied separately. Both 5173 and 5273 are listed as mating products, subject to the complete application.

Have a genuine interface problem?

Start with the existing platforms. CiiLOCK can review selective system-development requirements where they do not fit.
