Product Description

The High-strength Friction Stay for Top-hung Window SUS304 by Kingbo is a professional-grade friction hinge engineered specifically for top-hung window stress conditions. Founded in 2009, Kingbo is a door and window hardware manufacturer with around 100 patents and exports to global markets across 36 countries.

Unlike standard casement hinges, top-hung windows concentrate load on the lower support structure. To address this, Kingbo designed a reinforced system featuring a 4mm bearing plate and backward-lifting slider, ensuring stable performance for sashes up to 1000mm in height and 1200mm in width.

Core Materials

Material selection directly impacts durability and performance.

This friction stay is manufactured from SUS304 stainless steel (18% chromium, 8% nickel), providing strong corrosion resistance for coastal and humid environments.

Key material features:

· Titanium-coated friction block for enhanced surface hardness and anti-squeak performance

· Nylon + stainless steel tail slider for silent and self-lubricating operation

· High-cycle durability suitable for frequent-use environments such as hotels and offices**

· Stable friction coefficient across long-term operation

The combination of titanium coating and nylon-stainless steel structure ensures consistent performance even after thousands of cycles.

Product Features

1. Silent Sliding Mechanism: Equipped with a nylon-stainless steel slider at the tail, the stay operates quietly and features a backward-lifting structure that extends service life.

2. Reinforced Bearing Plate: With a 4mm thick bearing plate, this high-strength friction stay for top-hung window provides outstanding structural support—a visible advantage to end-users.

3. Unique Fixing Plate: The specially designed fixing plate allows installation on both sides of the sash groove, facilitating future maintenance or replacement without screw damage.

46. Classic and Dependable Design: Traditional structure ensures stability and reliability, recommended for top-hung windows with maximum dimensions of 1000mm (H) × 1200mm (W).

5. Opening Angle & Stack Height: Provides an opening angle of 25–30° and a stack height of 16.5mm.

6. Multiple Size Options: Available in 10″, 12″, 14″, 16″, and 18″ sizes. Model FJ-2214 corresponds to the 14″ version.

Designed for Top-Hung Load Bearing

Top-hung windows often suffer from sash sagging, sticking, or screw loosening due to uneven force distribution during opening. The High-strength Friction Stay for Top-hung Window SUS304 solves this with a reinforced structural design.

Key functional improvements:

· 4mm reinforced bearing plate for improved load resistance

· 25°–30° controlled opening angle for safer ventilation

· 16.5mm stack height for flexible installation space

· Stable load distribution for reduced deformation risk

Kingbo emphasizes engineering honesty by clarifying that this hinge is part of a system and not the sole load-bearing component in top-hung window structures.

Applications

The High-strength Friction Stay for Top-hung Window SUS304 is widely used in architectural projects requiring durability and safety.

Typical applications include:

· High-rise residential buildings with strong wind load exposure

· Commercial curtain wall systems requiring stable ventilation control

· Coastal and humid environments such as Southeast Asia and Middle East regions

· Hotel and office buildings with frequent window operation cycles

· Window renovation projects where easy replacement without frame damage is required

A key advantage is its flexible fixing structure, which allows installation without full window disassembly during retrofit projects.
