The Concealed Hydraulic Door Closer by Tag Hardware is a bottom patch fitting for doors. Unlike the conventional floor spring, the hydraulic door closer requires no cavity on the ground for installation, making the process quick and creating an aesthetically appealing seamless doorway. The absence of an opening on the floor allows for a cleaner surface with minimal accumulation of dust or water, making this product ideal for places requiring extra hygiene such as hospitality and health care.
