Description

Alaks TS143 Rear Fixing Stopper | Heavy‑Duty Lift & Slide Systems

The Alaks TS143 Rear Fixing Stopper is a specialized hardware component engineered to control the end‑of‑travel position in ultra‑heavy sliding and Lift&Slide systems.

In architectural sliding systems where the sash dimensions are large, heights are considerable, and glazing weight is extremely high, precise control of the terminal stopping point becomes critically important. Uncontrolled impact at the end of the track can transmit excessive force to the frame profile, sliding track, bottom rollers (carriages), and hardware assemblies, potentially causing profile deformation, premature hardware wear, or long‑term operational issues.

Designed specifically for high‑load applications, the TS143 Rear Fixing Stopper features a reinforced structure and optimized dimensions to function as a reliable final stopper and stabilizing fixing element. By absorbing rebound forces and dampening impact energy, it prevents direct collision between the sash and the frame, ensuring a controlled and cushioned stopping motion.

Its engineered design guarantees high mechanical stability, resistance to loosening over extended operation, and contributes to silent, smooth sliding performance. For projects utilizing the latest generation TS143 Lift & Slide systems, this component is considered an essential element for completing the safety, durability, and operational integrity of the hardware set.

Frequently Asked Questions:

What is the primary function of the TS143 Rear Fixing Stopper?

It defines the final stopping position of the sash while absorbing end‑of‑travel impacts to prevent harsh collision with the frame.

Is this component exclusive to the TS143 system?

Yes. Its dimensions, structural strength, and installation geometry are specifically engineered for the TS143 Lift & Slide series.

How does it extend the lifespan of hardware components?

By eliminating terminal impacts and preventing shock transfer to the hardware assembly, operational stress on the system is significantly reduced.

Is installation of this stopper necessary?

For heavy and large‑format sliding sashes, it is strongly recommended. Operating without it may lead to damage to the rollers, track, and frame profiles.

Is installation complicated?

Not at all. Installation is straightforward and requires only a few screws. The stopper is positioned at the designated end point of the sliding track and securely fastened.
