The Brass Dust Proof Socket with Plate is a dust protection accessory for doors made of brass. The product consists of two main components: the dust-proof socket and the plate. The dust receptacle measures 55mm x 23.5mm, the fixing plate measures 79mm x 39mm, and the surface is equipped with 4 mounting holes. The dust protection of the Dust Proof Socket with Plate is achieved through a mechanically sealed construction. When the pin enters the inside of the socket, the gap between the pin and the inner wall of the socket is controlled within 0.3mm. The contact surface between the fixing plate and the door frame is designed with a flat design to ensure no gaps after installation. This product is suitable for both wooden and steel doors. The dustproof socket accommodates standard pins with a diameter of 18-22mm. The Dust Proof Socket with Plate can be used with most standard concealed latches.

Product Advantages
1.Material Durability
The brass construction endows the Dust Proof Socket with Plate with exceptional corrosion resistance. When used in humid environments, the brass surface naturally forms a protective film, preventing further oxidation. The product boasts high tensile strength, withstanding frequent insertion and removal operations. Brass's wear resistance ensures the contact surfaces of the pins remain smooth even after prolonged use, maintaining full functionality.
2.Sealing Performance
Precise dimensional control enables the Dust Proof Socket with Plate to achieve effective sealing. The clearance between the socket cavity and plug is less than 0.3mm, a precision that blocks the majority of dust particles. The close contact between the fixing plate and door frame prevents lateral gaps. Upon full installation, dust prevention efficiency at the door gap exceeds 95%.
3.Installation Convenience
Standardised dimensions ensure a simple and swift installation process. The four mounting holes on the fixing plate are symmetrically arranged, eliminating the need to distinguish installation orientation. The plate dimensions of 79mm x 39mm cover most pre-cut door frame openings. The product features integrated installation alignment marks, allowing fitting with 2.standard tools. No specialised skills or equipment are required throughout the installation process.
Product Applications
1.Residential Interior Doors
In domestic settings, the Dust Proof Socket with Plate is primarily used on doors to rooms requiring cleanliness, such as bedrooms and studies. It effectively prevents floor dust from entering through door gaps, reducing routine cleaning frequency. The brass finish harmonises with interior door décor, maintaining overall aesthetics.
2.Commercial Door Fittings
Concealed latches are commonly used in office and meeting room doors. The Dust Proof Socket with Plate integrates seamlessly with these latches, preserving a tidy appearance when doors are closed. Particularly suited for installation at frequently used floor bolt positions, it significantly improves cleanliness in these areas.
3.Public Building Door Systems
Public buildings such as schools and hospitals demand high hygiene standards. Installing the Dust Proof Socket with Plate on doors in these settings reduces the likelihood of dust transmission. Its robust construction withstands frequent use in public environments, maintaining long-term dust prevention.
Product Installation
1.Installation Preparation
Before installing the Dust Proof Socket with Plate, confirm the latch position. Close the door panel so the latch tip contacts the frame, marking the latch centre point. Using this point as the centre, mark out a 55mm x 23.5mm opening area. Chisel a 15mm-deep installation slot within the marked area, ensuring the slot base is level.
2.Fixed Installation
Position the dust-proof socket within the prepared installation groove and verify it sits flush. Cover the socket with the fixing plate, aligning the mounting holes. Secure the plate by first fixing the two diagonal holes with screws, ensuring the plate adheres completely to the door frame surface. Finally, tighten all screws to a torque of 1.5 N·m.
3.Commissioning and Inspection
After installation, conduct a switch test. Slowly close the door leaf, observing whether the latch engages smoothly within the Dust Proof Socket with Plate. Should any obstruction occur, slightly adjust the fixing plate's position. Upon completion of testing, apply sealant around the fixing plate's edges to ensure complete sealing. Finally, clear any debris generated during installation to finalise the process.
