Metal Corner Joint Fuji 2000

The ALAKS FUJI 2000 Metal Corner Connector is engineered for hinged thermal‑break systems, featuring the advanced Fuji push‑button mechanism. Once positioned inside the aluminum profile and the Allen screw is turned, the steel buttons expand outward, locking onto the inner walls. This dual‑side engagement creates a precise draw‑in effect, pulling mitred joints together until the corner gap reaches zero — delivering seamless alignment and maximum structural integrity.

This product has only one variant.

Description

Alaks Fuji 2000 Metal Corner

In the assembly of thermal-break aluminum doors and windows, the quality of corner joints directly affects the strength, sealing, and long term durability of the structure. The Fuji 2000 metal corner connector, equipped with the engineered Fuji push button mechanism, provides a precise, adjustable, and exceptionally strong corner connection.

How the Fuji (Push Button) Mechanism Works?

Unlike simple corner connectors that only sit inside the profile cavity, in this model:
1.   The corner connector is inserted into the hollow chamber of the aluminum profile.
2.   By tightening the Allen screw, the internal steel buttons expand outward.
3.   These steel buttons lock firmly against the inner profile walls.
4.   The two sided locking action creates a draw in effect, pulling the profiles tightly together.
As a result, the miter joint becomes fully seated, seamless, and structurally stable. This prevents long term corner loosening and increases assembly accuracy.

Why This Matters in Thermal-Break Systems?

In thermal-break systems:
• The sash weight is higher
• Multiple internal chambers exist
• The polyamide strip makes joint precision critical
• Even a small corner error causes leakage, sagging, or deformation
The Fuji mechanism, with its mechanical locking and inner tension, ensures a rigid, engineered corner joint.

Key Advantages of Fuji 2000:

✓ Fast installation using only one Allen key
✓ No special machinery required
✓ Significant time savings during workshop assembly

Re-adjustability and Fine Tuning:

Unlike permanent joints, this connector:
• Can be opened
• Allows angle correction
• Supports re-adjustment for high precision projects
This makes it ideal for industrial grade or large scale assemblies.

Technical Specifications:

• Horizontal arm length: 50 mm
• Vertical arm height: 40 mm
• Body thickness: 4 mm
• Equipped with an adjustable Allen screw
• Features steel locking buttons
• Suitable for hinged thermal-break systems
The Fuji 2000 metal corner, with its push-button tension mechanism, is one of the most professional and reliable corner connectors for hinged thermal break frames. Precision fitting, easy installation, adjustability, and strong structural performance make it an ideal choice for heavy and high accuracy frames.
