Bathroom Door Lock Thumb Turn Features:

Excellent corrosion resistance

The Bathroom Door Lock Thumb Turn is made of satin stainless steel, which is mainly composed of chromium, nickel and iron, with chromium content as high as 16% - 18% and nickel content between 8% - 10%. This material makes it have excellent corrosion resistance. In the salt spray test, it can still show no obvious rust or performance degradation after 720 hours of continuous testing. Compared with ordinary carbon steel door locks, its corrosion resistance is improved by 5-6 times, and it can maintain good appearance and performance even in the humid environment of the bathroom for a long time, ensuring the stability and reliability of the door lock.

Excellent durability

The door lock has undergone rigorous durability testing and can withstand more than 100,000 locking and unlocking operations without functional failure or part damage. Its internal mechanical structure uses precision-machined stainless steel parts, which fit tightly and reduce wear and jamming. For example, in frequently used public bathrooms or hotel bathrooms, this door lock can maintain a long-term stable working state without frequent replacement, which greatly reduces the maintenance cost and replacement frequency, and provides users with long-term and reliable use guarantee.

Fine surface treatment process

The satin stainless steel surface treatment process of the door lock not only gives the product an elegant appearance, but also has many practical advantages. This process forms a uniform oxide film on the surface of stainless steel, so that the surface hardness of the door lock reaches 350-400HV, which is about 30% higher than the surface hardness of untreated stainless steel. This oxide film can effectively resist scratches and wear in daily use, and can maintain the gloss and texture of the surface for a long time even with frequent touch or cleaning. At the same time, the satin treatment also has good anti-fingerprint performance, and the fingerprint residue rate is only 15%-20% of polished stainless steel. It is more convenient and quick to clean, and it can be restored to brightness with just a simple wipe.

Precise size design

The size of the product is 50×50mm, the thickness is 5.08mm, the width of the panel is 20.00mm, the height is 50.00mm, and the diameter of the mounting hole is 23.50mm. These dimensions are carefully designed and strictly controlled, with a tolerance range of ±0.1mm. During the installation process, this precise size ensures that the door lock is perfectly matched with the door body and the lock body, and the installation is convenient and firm. For example, when making a customized bathroom door, the carpenter can process the door opening according to the precise size of the door lock to ensure that the door lock fits tightly after installation, without looseness or excessive gaps, etc., which improves the stability and safety of the door lock and ensures the overall aesthetics of the door.

Convenient operation experience

The operation design of the Bathroom Door Lock Thumb Turn fully considers the user's convenience. The thumb turntable adopts an ergonomic curve design with a diameter of 23.50mm, a smooth surface and moderate friction. The user can easily rotate it with the thumb, and only needs to rotate 90° to complete the locking or unlocking action. The design of the release button is also very clever. It only requires 15-20 Newtons of force when pressed, which is easy for even children or the elderly to operate. Compared with traditional key locks, this design does not require carrying keys, avoiding the trouble of losing or forgetting keys. At the same time, it can respond quickly in emergency situations to ensure the safe evacuation of personnel.

Good sealing performance

The door lock has excellent sealing performance, reaching the IP66 protection level, which can effectively prevent moisture and dust from entering the lock body. In a humid environment such as the bathroom, good sealing performance ensures that the electronic components and mechanical parts of the door lock are not eroded by moisture and water, extending the service life of the product. After testing, after 10 minutes of continuous water spraying, the inside of the lock body remains dry without any moisture intrusion. Compared with door locks with non-sealed designs, its failure rate is reduced by about 70%-80%, reducing the frequency of maintenance and replacement, and providing users with long-term and stable use guarantees.

High load bearing capacity

The lock body structure of the door lock is reasonably designed, using high-strength stainless steel and precision machining technology. After testing, a single Bathroom Door Lock Thumb Turn can withstand a pulling force of 60 - 100 Newtons without damage or deformation. This means that even under frequent use or accidental collisions, the door lock can remain stable and will not fail due to excessive load. For example, in bathroom doors in public bathrooms or gyms, due to the large flow of people, the door lock needs to withstand more times of use and external force impact. The use of this high load-bearing door lock can effectively reduce the risk of damage and ensure the long-term normal use of the door lock.

Multiple surface treatment options

This product offers a variety of surface treatment options, including Black PVD, Matt Antique Brass - PVD, Polished Brass / PVD, Polished Stainless Steel, Satin Brass PVD and Satin Stainless Steel. The surface hardness after Black PVD treatment can reach 2000 - 3000HV, with excellent wear and corrosion resistance, while presenting a stylish black appearance. Matt Antique Brass - PVD treatment can give the product an antique brass color. After PVD treatment, its wear resistance is about 3-5 times higher than that of traditional electroplating. Polished Brass / PVD treated products have a mirror-like surface and bright color. After PVD treatment, its corrosion resistance is greatly enhanced and can resist the erosion of humid environment. Polished Stainless Steel treated products have a smooth surface, good reflective effect and modern sense. Satin Brass PVD treatment combines the color of brass and the texture of satin. After PVD treatment, its wear resistance and corrosion resistance are significantly improved. Satin Stainless Steel treated products have a delicate satin texture, comfortable feel and excellent anti-fingerprint performance.
