The mortise lock ES 436 is suitable for rebated bathroom doors or WC doors because the lower nut can be used to mount a special WC fitting or a bathroom rosette fitting. The lock also enables screw-on fittings and rosette fittings to be fitted easily thanks to the standardised holes in accordance with DIN 182511 (Class 1). The stainless steel faceplate ensures it is durable and gives it a high-quality look. The mortise lock can also be easily fitted in any door due to the rounded faceplate. The lock case is enclosed to protect the mechanism from dirt.
