中山市雷茵五金制品有限公司(RAYEN) is based in Xiaolan, Zhongshan, Guangdong. We have been making locks since 1999, and tooling, pressing, assembly and inspection all happen on one site. Xiaolan is the densest mechanical-lock district in China — die casting, plating and heat treatment are all within half an hour of the works.

The range covers panic exit devices, knob locks, lever handles, mortise cases, cylinders, hinges, glass door fittings, door closers and bathroom hardware. We manufacture to your drawing, to your sample, and under your brand.

Every model on this site has its own specification table. A dimension we have not confirmed is shown as a dash rather than an estimate — hole positions and sizes on metal hardware are fixed the moment the tool is cut, and getting one wrong costs a shipment, not a return.
