Description

Alaks TS77 Plastic Sash Fixing Stopper

The TS77 plastic fixing stopper is a small yet highly essential component in the assembly of TS77 sliding window systems. In configurations where one sash must remain fixed, screws or standard fasteners alone are not sufficient.
Installed in front of the fixed sash and engaged with both the upper and lower rails, this component fully secures the sash in place, preventing movement, vibration, or sliding. It functions as a fixed sash retainer, ensuring stable, quiet, and precise window operation.

What Is the Function of the TS77 Stopper?

In two or three panel sliding windows, typically one sash is fixed while the other(s) move. If the fixed sash is not properly secured, vibration or displacement may occur during operation or under wind pressure.
The precise engineering of this product ensures:
•   Complete locking of the fixed sash in position
•   Prevention of horizontal movement or sliding
•   Reduction of vibration and profile noise
•   Proper control of pressure caused by moving sash operation
•   Stable and accurate overall sliding performance

Why Is This Stopper Essential in the TS77 System?

Without a proper fixing stopper—even when other hardware components are high quality—the following issues may arise:
•   Vibration of the fixed sash during opening and closing
•   Noise during sliding operation
•   Reduced sealing performance
•   Air and dust infiltration
•   Shortened hardware lifespan
The Alaks TS77 stopper fully secures the fixed sash, allowing the window to function as a completely stable and immobile surface while maintaining insulation performance.

Role in Sliding Window Performance:

In modern sliding systems, precise coordination between rails, rollers, locks, and fixing components is critical. The TS77 stopper enables the fixed sash to act as a stable structural support, allowing the moving sash to operate smoothly and without interference.
It ensures:
•   Smoother sliding motion
•   Reduced stress on rails and rollers
•   More precise locking and sealing performance
