A sliding glass door stopper is a fixed device installed on sliding glass doors to limit the maximum sliding range of the door leaf, preventing excessive sliding from causing glass collisions or structural damage. It is typically made of high-strength stainless steel and uses a precise mechanical structure to control the door's stop position. Its metal-rubber design provides a cushioned feel during opening and closing, maintaining stable resistance and tightness even after prolonged use, enhancing the comfort and lifespan of the entire door system.

High-Strength Construction

The Sliding Glass Door Stopper is made of SUS304 or SUS316 stainless steel, with tensile strengths of 520 MPa and 560 MPa, respectively, capable of withstanding the continuous impact and friction of heavy glass doors (8 to 12 mm thick).

Precise Position Control

The mechanical position control in the Sliding Glass Door Stopper's design offers a precision error of less than ±0.2 mm, effectively preventing secondary impacts caused by door inertia. A 40.5 mm installation depth and 23.5 mm lateral support distance ensure balanced force distribution, reducing the risk of pressure on the glass edges.

Buffering Protection Design

A high-density rubber pad embedded in the top with a hardness of 70 ± 5 Shore A effectively absorbs up to 40% of sliding impact energy. This structure prevents the door from directly impacting metal components, protecting the glass edges from cracking.

Wear-Resistant Surface Treatment

The surface is finished with a satin brushed finish, achieving a surface roughness of Ra ≤ 0.8 μm, effectively reducing fingerprints and scratches and enhancing the visual quality. After 500 hours of salt spray testing, it meets the corrosion level 9 standard and is suitable for coastal or high-humidity environments.

Easy Installation and Maintenance

The installation hole diameter and positioning dimensions are highly accurate, with an error of less than ±0.1 mm. Installers can quickly complete positioning and fixing, saving construction time. Subsequent maintenance requires only regular cleaning and tightening of screws, reducing maintenance frequency.

Bathroom Sliding Doors

The Sliding Glass Door Stopper is suitable for use with the top round tube guide system of independent shower enclosures. By providing a stop between the fixed glass and the movable door, it prevents the door leaf from impacting the wall and faucet area, reduces the risk of micro-chipping of the glass edge, and maintains a safe opening and closing distance. Humid and steamy environments require high corrosion resistance from metals. The use of SUS316 improves stability in chlorine-containing vapor conditions, facilitating long-term maintenance in hotel, apartment, and home bathrooms.

Balcony Sliding Doors

The Sliding Glass Door Stopper is used for sliding glass doors in balcony and terrace areas. Combined with outdoor stainless steel guide rails, the stopper stops the door leaf at a preset position in high winds, preventing it from being pulled against guardrails or corners.

Office Partitions

Sliding Glass Door Stoppers are installed on sliding glass partition doors in office buildings to ensure consistent access widths with fire escape routes. The stoppers provide low repeatability, ensuring stable operation of door stops or door closers, reducing door gap variations and noise caused by travel fluctuations, improving order and quietness in open office areas, and facilitating cleaning and inspection management.

Shop Fronts

Sliding glass doors used in shopping malls and street shops provide a clear demarcation between open and closed positions. Fixed alignment allows for easy alignment of floor stickers and doorstop signs, reducing collisions during customer entry and exit and during logistics handling. The brushed stainless steel finish harmonizes with commercial environments, is fingerprint-resistant, and easily removable, keeping the front of the shop looking clean and tidy for a long time.

Regular Cleaning

Wipe the contact surfaces between the main body and the guide rails every one to two weeks with a neutral detergent and a soft, lint-free cloth. Soften surface stains with warm water before removing to prevent particles from scratching the wire surface. After cleaning, wipe dry with a dry cloth to prevent water marks from forming mineral deposits in the metal grain. Avoid using strong acids, bases, or chlorine-based cleaners, as they may damage the stainless steel's passivation film.

Corrosion Protection

Perform surface maintenance every three to six months. First, clean the surface, then apply a thin layer of stainless steel care oil or microcrystalline wax to create a hydrophobic layer, reducing the retention of salt spray and perspiration. In high-chloride environments such as those near the sea or swimming pools, increase this to monthly. Also, check the passivation status. If any dark spots are found, immediately clean them with a scouring pad and stainless steel cleaning paste along the grain, then recondition.

Tightening Re-inspection

Quarterly, check the tightening status of the set screws and any signs of movement in the clamping position. Use a torque wrench to re-tighten to four to five Newtons to ensure sufficient preload. Check the relative angle between the stopper and the guide rail to ensure it is perpendicular to the travel direction to avoid abnormal wear of the buffer pad due to eccentric loading. If the threads are not engaging smoothly, clean them, apply extreme pressure lubricant, and then re-engage them.

Pad Maintenance

Stop pads should be replaced promptly if they are hardened, cracked, or if the indentation depth exceeds one-third of the original thickness. Use only warm water and a neutral cleaner when cleaning to avoid solvents that may degrade the rubber. Prolonged ambient temperatures above 80°C or below -20°C will shorten the lifespan. Inspection intervals should be shortened to maintain a smooth and elastic contact surface.

Guide Rail Calibration

Inspect the guide rail straightness and bracket tightness every six months. Use a ruler and feeler gauge to check the rail surface deviation within 500 mm before and after the stop point. Keep it within 0.5 mm to prevent the stop point from shifting due to localized track sinking. If the bracket is loose, unload it before re-tightening it. Adjust the bracket spacing if necessary to keep the door's operating resistance and stop impact under control.
