Plastic Corner Joint EM38-21
Description
EM 38-21 Plastic Corner – Specialized Internal Connector for TS77 Aluminum Systems
Internal corners are among the most critical components of aluminum door and window hardware; small yet decisive parts that determine the final frame quality, corner stability, and structural lifespan. The EM 38-21 plastic corner is a specialized model engineered for full compatibility with the TS77 system, offering stable, play-free performance. It is the ideal choice for professional manufacturers of 77-series aluminum systems who prioritize assembly precision.
Exclusive Design for the TS77 System:
The TS 77 aluminum system features a profile structure with internal chambers and dimensions different from lighter series. Using generic or standard corners in this system risks looseness, frame sagging, or twisting. The EM 38-21 corner is manufactured precisely to match the internal geometry of the TS 77 profile, locking perfectly into the internal groove.
Results of this design:
• Creates a completely rigid 90-degree joint.
• Prevents frame corner twisting.
• Increases stability against the weight of large sashes.
• Ensures higher precision in final assembly.
Material: High-Strength Engineered Plastic:
This corner is made from reinforced “unbreakable” engineering plastic, featuring:
• High resistance to longitudinal stress and pressure.
• Anti-crack and anti-shatter properties under force.
• Stability against temperature fluctuations and UV radiation.
• Long-term durability without becoming brittle.
• Precise dimensional tolerances for a zero-play fit inside the profile.
The reinforced structure ensures that the pressure applied during the opening and closing of sashes is distributed uniformly across the corner surface.
Applications:
• Internal 90-degree connection of two TS 77 frame profiles.
• Sash and frame assembly for 77-series systems.
• Suitable for medium to heavy-duty doors and windows.
• Ideal for industrial production lines and professional assembly workshops.
• Prevents profile looseness and deformation over time.
Advantages:
• Fast & Easy Installation: No complex tools required.
• System-Specific Design: Tailored for the TS 77 profile series.
• Mechanical Durability: High resistance to environmental and physical stress.
• Lightweight: Does not add unnecessary load to the structure.
• High Stability: Perfect for luxury projects or large-span openings.
