The Brass Dust Proof Strike with Plate is a dust door accessory designed for wooden and steel doors, with the core function of solving the problem of dust accumulation in latch pores and door frame deformation through a sealed structure and reinforced base plate. The product consists of two parts: the main dust collector (55mm×23.5mm) and the supporting base plate (79mm×39mm), both cast in high-quality brass, with a surface that is precisely polished and plated, which has both corrosion resistance and mechanical strength. The main dust trap adopts a spring-loaded plunger system, when the latch is retracted, the plunger automatically falls back to the plane of the bottom plate, forming a physical barrier, effectively blocking dust, debris, insects and humid air from entering the latch track; The bottom plate enhances the support force of the door frame by increasing the contact area (79mm×39mm) to prevent the deformation of the door frame or the expansion of the hole position caused by frequent opening and closing.
Compared with traditional dust filters, this Dust Proof Strike with Plate significantly improves structural stability through the base plate design, and the brass material provides stable mechanical support, especially suitable for high-frequency door opening and closing door systems in commercial buildings.

Product advantages
As the protective core of the door control system, this Brass Dust Proof Strike with Plate achieves dual upgrades in functionality and durability. The spring plunger structure has an automatic reset function, and the hole is immediately closed after each pin is retracted to avoid mechanical resistance caused by dust accumulation and significantly reduce maintenance frequency; The bottom plate disperses pressure by increasing its size, effectively solving the deformation problem of door frames caused by long-term stress, especially suitable for steel or heavy-duty wooden door scenarios.
In terms of material, the brass substrate, after coating treatment, has both hardness and weather resistance, which can resist moisture, salt spray, and chemical corrosion, avoiding structural looseness caused by rust. For example, in commercial buildings in coastal areas, this product can resist salt spray erosion for a long time and maintain structural integrity; In high humidity environments such as chemical parks or swimming pools, its corrosion resistance can also ensure long-term stable operation.
Product Application
This Brass Dust Proof Strike with Plate is widely used in commercial, industrial, and residential door control scenarios, becoming a standard configuration for improving the reliability of door systems. In commercial buildings, its dust prevention and reinforcement functions can simultaneously solve cleaning and structural problems, especially suitable for high-frequency opening and closing areas such as hospital operating room access doors, data center room doors, and hotel room doors. For example, hospital operating rooms need to strictly prevent microorganisms from spreading through plug holes, and this product effectively blocks bacterial transmission pathways through a sealed design; Data centers rely on their dust control capabilities to avoid potential threats from dust to precision equipment.
In industrial environments, dust collectors combined with heavy-duty plugs form a durable door control solution. Food processing plants, pharmaceutical workshops, and other places that require strict dust control can meet the standards by installing this product; In heavy-duty door scenarios such as logistics warehouses or car repair workshops, the reinforcement effect of the bottom plate can prevent door frame deformation and ensure long-term sealing. In addition, public buildings such as educational institutions and shopping centers have also deployed this product to reduce cleaning and maintenance frequency and improve operational efficiency.
In the residential field, this product is suitable for exterior door systems in humid coastal areas or areas prone to sandstorms. When used with automatic locking, it can form a seamless dust barrier to prevent pet hair and small garbage from entering the locking track; The enlarged size of the bottom plate is more suitable for the renovation project of old door frames, extending the service life of the door body by dispersing pressure. Its antibacterial coating is also suitable for high-end apartments and villas, meeting users' needs for a healthy living environment.
Product Installation
Before installation, it is necessary to prepare an electric drill, a Φ 4mm drill bit, a Phillips screwdriver, a level, and a positioning template (provided as a set). Firstly, place the bottom plate (79mm × 39mm) at the preset position at the bottom of the door frame, and use a positioning template to mark the screw hole positions (with a spacing of 65mm). It is recommended that the hole depth be 20mm to ensure the fixing strength; After drilling, clean up the debris and preliminarily fix the bottom plate with stainless steel screws (provided) to ensure that it is level and not tilted.
Insert the main dust collector (55mm × 23.5mm) into the center groove of the bottom plate, adjust the plunger opening to align with the pin head, mark the dust collector screw hole position again using the positioning template, drill the hole and tighten it with M4 screws. Verify the vertical and unbiased movement trajectory of the plunger using a spirit level, manually operate the pin several times to ensure smooth lifting and no jamming of the plunger. If the door frame material is wood, it is necessary to inject wood glue into the screw holes to enhance the nail grip; For metal door frames, it is recommended to use rivets instead of screws to improve vibration resistance.
After installation, the residual metal debris around the plunger can be cleaned with a soft bristled brush to avoid abnormal noise during the initial use stage. In terms of daily maintenance, it is recommended to check the rebound force of the plunger and the fixing status of the bottom plate every 6 months. If spring fatigue or loose screws are found, they can be repaired by adjusting the screws or applying adhesive, without the need to replace the entire machine. In areas with severe sandstorms, the plunger track can be regularly cleaned with compressed air to ensure continuous and effective sealing performance.
Through the above design, this Brass Dust Proof Strike with Plate not only achieves a balance between functionality and durability, but also becomes an indispensable comprehensive solution in commercial and industrial door control systems through the reinforcement effect of the bottom plate and the sealing performance of the dust collector.
