Schlage 20-787-UNLK 626 Classic Quad Primus 1-1/8" mortise cylinders with UNLK keyway.

Whoa, what language is this dude speaking you might be wondering? Let me break it down for you:
  • Schlage is a world wide & world class lock manufacture.
  • Classic is a brass bodied (shell/housing) . The current product is called Modular. Contact me if you want more data.
  • Quad is a very restricted class/family of keyways and keys. NOT available at big box stores or 99% of other places you get keys.
  • Primus is Schlage high security product. It has a second set of pins & a sidebar that works with a milling down the side of the blank. This cylinder is only operated by a Schlage Quad Primus key.
  • 1-1/8" is the length of the cylinder. See the pic on how it is measured. They are from the back side of the head to the end of the tailpiece.
  • 626 is the finish. This is called brushed/satin chrome. It is one of the most durable finishes made.
  • Mortise cylinders are threaded and generally fit into a mortise lock. They come in all different styles & brands. They are also used in other applications like switch locks Etc.
  • UNLK is the specific keyway that fits this cylinder.
FYI: I have more Quad, Quad Primus blanks and cylinders posted or will post soon.
Here is the BOLD print. I do NOT deal in fine print, diversions or subterfuge! What you see is what you get, nothing more or less!
  1.  These cylinders are NOS & NIB. They are ready to go back to work!
  2.  They do NOT come with keys.
  3.  I have UNLK key blanks for these cylinders listed separately.
  4.  They do come with rings/collars & the spring.
  5.  They have what ever tailpieces/cams that are on them. I can switch to any popular cam that you may want IF you tell me when you purchase the cylinder(s).
  6.  I can rekey them for you, cut keys and consult with you on what your needs are. That is NOT included with this posting.
I do not take returns. Please ask all of your questions in advance of hitting the purchase button. I am a working locksmith and can answer any additional questions you have about the product, its use or your intended use. I do not take returns. I only will take a return if I have lied about the product or grossly misrepresented the product. Example: These locks were used on King Tuts tomb to protect his remains from invaders 3,000 years ago in the great pyramid. They were not that is a lie!
Let's have a win win deal and not have me turn into a first class ahole after the fact when you try to return the cylinders because they will not work in your Lambo.
