Exterior Passage Door Lever is composed of high-strength metal handle, base rose cover, connecting shaft core and standard channel lock tongue. It supports compatible use with a variety of door materials. It is a lock-free door handle component designed for residential exterior doors, commercial exterior channel doors, and public entrances and exits. It is usually used in areas where locking function is not required but door opening and closing control is required.
Exterior Passage Door Lever is cast with high-density zinc alloy or stainless steel, and the surface of the handle body is treated with multi-layer electroplating + anti-corrosion coating to effectively prevent erosion by natural environments such as rain, ultraviolet rays, wind and sand. The product has passed the 72-hour salt spray test and UV aging test to ensure that the structure is stable and the appearance is intact under conditions of high humidity, high temperature, strong wind, etc.
The applicable door body thickness range is 35mm-60mm. Whether it is a solid wood door, a fireproof steel door or a composite aluminum door, it can be stably installed to ensure unobstructed passage. In areas with drastic temperature differences or severe environmental pollution, the high corrosion resistance of the Exterior Passage Door Lever is particularly prominent, making it an ideal option for long life and low maintenance.
The Exterior Passage Door Lever adopts a reinforced stainless steel shaft core + high-precision gear structure to ensure a smooth feel during daily repeated opening and closing. The handle rotation angle is precisely controlled between 45° and 60°, and with a ball bearing reset system, it can achieve fast rebound and silent operation. Actual measured data shows that the product has no obvious loosening or failure in the 100,000 opening and closing cycle test, and its durability is much higher than the industry average standard.
In addition, the base of the handle and the door body adopt a four-point bolt fixing structure, which can maintain a firm state even under high-frequency passage or mild external force impact, avoiding safety hazards caused by loosening. This technology is particularly suitable for environments with high usage intensity such as large commercial doors and hotel lobby doors.
Exterior Passage Door Lever provides a variety of surface treatment options, including brushed nickel, bright chrome, matte black, electroplated gold, PVD titanium gray, etc. All surfaces are anti-fingerprint treated and nano-coated for protection, and are not easy to leave oil stains and scratches during use. The surface coating thickness is controlled at more than 8μm, which effectively extends the product appearance life.
Exterior Passage Door Lever is designed to take into account both aesthetics and grip comfort. The handle diameter is controlled between 18mm-22mm, which conforms to the ergonomic palm grip size standard, and the operation feels soft, suitable for people of different ages. In mid-to-high-end residential projects in Europe and the United States, such products are often used as high-end hardware for exterior doors.
Exterior Passage Door Lever supports customer customized LOGO printing, independent color box packaging design, and product appearance customization, which is widely used in overseas building materials wholesalers and engineering project customers. The product is mass-produced in accordance with ANSI/BHMA, CE, EN1906 commercial door hardware standards, with uniform hole spacing, matching screws, standard installation mold templates and other accessories, which facilitates rapid construction of the project.
At present, the monthly production supported by Exterior Passage Door Lever exceeds 400,000 sets, with a stable delivery cycle, suitable for cooperation with project-type, platform-type, and large-scale building materials chain brands. Whether it is a free brand mold or cooperation with large-scale real estate supporting projects, this product has strong delivery capabilities and customization flexibility.
In the Royal Thames Riverside high-end apartment project in London, UK, Exterior Passage Door Lever is used for the passage doors of all public floors and external corridors. These areas are exposed to wind, rain and moisture all year round, and place extremely high demands on hardware components. The surface of the Exterior Passage Door Lever adopts a brushed nickel treatment process, which is integrated with the building facade as a whole. The project construction party stated that this handle hardware has not had any corrosion, looseness, or jamming problems within 6 months, and the stability is extremely high.
During the expansion project of the University of British Columbia in Canada, a large number of corridor exit doors adopted this channel handle. Due to the rainy and humid climate in Vancouver, the school attaches great importance to the corrosion resistance of outdoor door hardware. The product is installed in the connecting passage between the library and the teaching building. The surface is coated with matte black electrophoresis, which perfectly matches the style of the building's glass curtain wall. The project construction party WestGroup said that the handle is quick to install and smooth to use, which perfectly meets the high-frequency use needs of the campus.
Nanyang Technological University has adopted this lockless handle system for a large number of exterior door hardware in the expansion of its office and teaching areas. The project location is in a high-humidity and high-temperature tropical environment all year round, which puts strict standards on the product's anti-oxidation performance. The Exterior Passage Door Lever adopts a PVD titanium surface with a long-lasting surface gloss, no spots or discoloration after long-term use, and perfectly meets the school's public passage door requirements.
In the high-end office building project of Applewood in Los Angeles, the Exterior Passage Door Lever was selected for the main entrance of the building and the entrances and exits of each floor, emphasizing its convenience of "keyless free passage". The handle is made of brushed stainless steel, with frameless glass doors and metal frames, taking into account both modernity and functionality. The project party A said: "This handle is reliable and stable in function, and has a simple business temperament in appearance. It is an ideal choice for current commercial buildings."
A large state hospital in Buenos Aires used this external passage handle when replacing its old passage door. The hospital corridor door needs to support the rapid passage of stretchers, and the handle needs to have a smooth opening and closing structure without a lock core to avoid accidental locking and congestion. After the installation of this handle, it can be used with the access control system to achieve one-way control, which greatly improves the hospital's emergency response efficiency and has won unanimous praise from medical staff.
