Concealed Latch Knob & Covers

All door concealed turn latch knobs and covers are in stock for fast delivery. We offer them in a chrome plated or cast stainless steel finish. The concealed turn latch knobs and covers will come with the security screws if needed.  We carry most manufacturers in stock, be careful most manufacturers look the same but are not. Most manufacturers have a name on the cover plate which goes on the outside of the door(1-1/2" diameter chrome plated or stainless steel). There should also be some numbers on the inside of the latch knob and cover plate, those numbers should be on our website in the search.
