Buffer EM 38-23

Description

Alaks EM 38‑23 Buffer 

The EM 38‑23 bumperis one of the essential components in TS77 sliding window systems. Its primary role is to absorb the impact of the sash at the end of its sliding path, prevent the heavy sash from colliding directly with the frame, and ensure perfect alignment between the sash and the frame angles.

If an appropriate bumper is not used, the sash typically hits the frame directly, leading to:

• Handle damage
• Roller misalignment
• Annoying impact noise
• Scratches, dents, or coating damage on the aluminum profile

The EM 38‑23 bumper is installed at both ends of the upper and lower tracks and acts like a small shock absorber, absorbing the kinetic energy of the sash at the end of its movement. Using impact‑resistant compressed polymer and UV‑resistant EPDM, this bumper provides complete durability against deformation, hardening of material, cracking, and sun exposure — making it the ideal choice for heavy, large, and frequently‑used sliding windows.

Unlike low‑quality market samples that break after a few cycles, the Alaks TS77 bumper is engineered to:

• Withstand continuous sash pressure
• Resist deformation in heat and cold
• Maintain its color and structural integrity under sunlight
• Lock firmly into the rail without requiring adhesive

It is designed so that installation requires no special tools; by simply pressing it into the profile slot, it locks mechanically and securely.
