Product Description

The 201 stainless steel heavy-duty thumb turn latch is a manual door-locking component designed for controlled environments. The thumb turn mechanism provides rotational actuation, allowing an operator to secure or release a door without external tools or electrical power. The product name specifies 201 stainless steel as the construction material, which is a common choice for hardware components requiring moderate corrosion resistance and machinability; however, exact chemical composition and surface finish should be confirmed with the supplier before specification.

As a heavy-duty variant, the latch is designated for applications where frequent mechanical operation is expected. The exact dimensions, mounting pattern, spindle length, rose size, and finish details are not listed in the current product data. Engineering teams should request a dimensional drawing and material certificate directly from the manufacturer to evaluate fit and function.

The unit is priced at US$0.50 per piece, which positions it as an economical component for volume procurement when integrated into door assemblies, retrofit projects, or OEM hardware kits. Pricing may vary with quantity, finish, or packaging requirements.

Applications

The latch is specified for two primary door categories. First, security doors benefit from a thumb turn latch that allows authorized personnel to lock and unlock from one side without a key, while maintaining a robust mechanical engagement. Second, cleanroom doors require hardware that minimizes particle traps and supports manual operation in controlled environments; the product name explicitly lists cleanroom doors as a target application.

For cleanroom environments, manual thumb turn latches are sometimes preferred over push-button or slam latches when controlled entry is needed, but this product's suitability for any specific cleanroom classification (such as ISO class or GMP grade) cannot be assumed without further certification data. Potential buyers should verify compatibility with their door thickness, preparation, and handing requirements, as well as any cleanroom protocol for exposed hardware surfaces.

The listing does not mention electrical integration, IP rating, fire rating, or cleanroom certification. This latch is therefore characterized as a purely mechanical component unless additional documentation is provided by the supplier.
