Locks

Corbin Russwin makes two basic lock types

• CL - Cylindrical Locks
• ML - Mortise Locks

Cylindrical locks get their name from the cylindrical bore hole in the door they mount to.

Corbin Russwin makes several series, each a different lock grade. CL3300, CL3500, CL3900 are a few examples, with CL3300 being the heaviest duty series.

To be technically correct, CL stands for Cylindrical Lever, as Corbin Russwin also makes CK series locks, Cylindrical Knob.

The knob versions are CK4200 and CK4400, with CK4200 being the heaviest duty.

Within any lock series, functions are designated by the last two digits of the model number.  A CK4210 is a passage function, with "10" designating passage.  Likewise, CL3351 is a entry function with "51" designating entry.  These last two digits do not change among series, so a "51" lock is always an entry lock, regardless of the series.

Mortise locks are the ML series, and get their name from the mortised hole in the edge of the door in which to mount the lock.

ML locks are harder to order as you not only have to specify function and lever style, but the type of escutcheon must also be noted.  Some escutcheons are round, some are rectangular and there are different sizes of each.  To complicate matters, you can order cast escutcheons, forged escutcheons, etc.

The levers (or knobs) plus escutcheons are called "trim", and Corbin Russwin trims are designated by three letters (GWC for example).

The first letter (G) stands for the knob or lever style.  In this case, G stands for the Global knob style.

The second letter (W) stands for the manufacturing process used, with W standing for Wrought. Another common designation is S for Steel.  So you will see trim designations such as CSA or CWA, which are the same thing except for the process used to make the trim.

The third letter describes the escutcheon.  These are difficult to explain and your best bet is to view the product catalog from Corbin Russwin.  We list all their product catalogs online.
