Satin Brass Stainless Steel Dust Proof Strike Gold Hardware for Concealed Flush Bolt-DDDP002

Product Features

1. Robust Durability

Forged from high-grade stainless steel, this product boasts exceptional structural strength and impact resistance. This enables the dust-proof flush bolt strike to withstand frequent latch impacts and daily wear, effectively resisting deformation, bending, or fracture. Its outstanding rustproofing and corrosion resistance ensure long-term performance stability even in humid environments or those with significant temperature fluctuations, significantly extending the product's service life. This forms a robust foundation for ensuring the door's secure, airtight closure over the long term.

2. Effective Sealing

The product's core value lies in its exceptional sealing performance. Its precision design and manufacturing process ensure a perfectly flush, tight engagement when the concealed bolt extends. This union forms an efficient physical barrier that actively prevents external dust, debris, fluff, and small insects from entering the interior through door gaps. This Dustproof Flush Bolt Strike is particularly suitable for spaces requiring high cleanliness standards, maintaining the door frame area clean and tidy over the long term while reducing the need for maintenance and cleaning.

3. Wide Compatibility

Boasting standard dimensions of 39mm x 19mm and a universal design, this product demonstrates exceptional adaptability. It fits seamlessly with doors of various materials, including timber and steel, meeting the installation specifications for most standard mortise bolts. This broad compatibility makes it an ideal choice for architects, fitters, and suppliers. Whether for new builds or replacements, it integrates effortlessly, significantly streamlining procurement and inventory management processes.

4. Aesthetic Finishes

While ensuring functionality, the product also prioritises aesthetic details. Its surface undergoes high-quality plating, offering popular finishes such as elegant Satin Brass. This finish not only harmonises with contemporary door hardware designs to enhance overall aesthetics but also provides an additional protective layer. This enhances scratch and fingerprint resistance, ensuring the product maintains a pristine visual appearance even after prolonged use.

Application Scenarios

1. Hospital Operating Theatres

Hospital operating theatres demand exceptionally stringent sterile environments. Installing the Dust-proof Flush Bolt Strike effectively seals door gaps, preventing external dust, bacteria, and contaminants from entering via airflow. This creates a highly clean, controlled environment for surgical procedures, serving as a vital auxiliary measure for medical safety.

2. Food Processing Facilities

Maintaining environmental hygiene is paramount in food production and packaging areas. This product prevents contaminants like dust and debris from infiltrating production zones through door gaps, complying with stringent food safety standards (e.g., HACCP, GMP) and safeguarding product quality alongside production line cleanliness.

3. Premium Office Buildings

Entrance doors and fire doors in high-end office buildings must not only ensure security but also maintain a pristine, professional appearance. The dust-proof flush bolt strike guarantees clean, sharp edges when doors close, preventing dust accumulation and reducing daily cleaning demands. It simultaneously elevates the building's overall aesthetic, enhancing both quality and modernity in architectural details.

4. Hotel Corridors

Fire doors in hotel corridors endure frequent operation while maintaining a quiet, refined environment. This dust-proof strike minimises interference from debris in the door gap, ensuring quiet, smooth closure while enhancing dust containment. This delivers a more comfortable, tranquil stay for guests.

Installation Guide

After fitting the concealed latch bolt to the door leaf, installing the dust guard (cover plate) is crucial for proper function. First, slowly close the door leaf, allowing the extended tip of the concealed bolt to leave a clear impression on the door frame. Use this impression as the centre point to determine the installation position for the Dustproof Flush Bolt Strike. Employ the cover plate itself as a template to precisely trace its outline and screw hole positions onto the door frame. Next, select an appropriate drill bit to create holes at the marked locations, ensuring the hole depth matches the cover plate thickness. Next, align the strike plate with the drilled holes and position it flush against the door frame. Finally, secure it firmly to the frame using the supplied screws. After installation, thoroughly test the door's opening and closing action multiple times, along with the bolt's extension and retraction. Ensure the bolt engages smoothly and precisely within the strike plate, achieving a perfect seal without any friction or obstruction.
