INTRODUCTION
Many customers appreciate the quality and durability of BEST cylindrical locks, but do not have the need for the BEST interchangeable core keying systems. For these applications, BEST offers 9K grade 1 and 7KC grade 2 cylindrical locks compatible with conventional Key-in-Knob (KIK) cylinders in a variety of trim styles. In addition, the 9K lock is capable of accepting removable cores in the proprietary Schlage large format figure-8 design.
BEST cylindrical locks can be ordered configured for use with OEM cylinders from another manufacturer (KIK or Schlage RC formats). Locks can also be ordered complete with a keyed KIK cylinder provided by BEST. In either case, BEST will provide all the necessary components to assure the cylinder and lockset operate together properly.
Many customers would prefer to use BEST locks, but have doors already prepared for a different through-bolt configuration. BEST now offers an alternative through-bolt option, enabling the 7KC and 9K to retrofit another common door preparation (2 3/4" through-bolt spacing).

HOW TO ORDER
How To Order: 9K
How To Order: 7KC
ALTERNATE THROUGH-BOLT (ATB) OPTION
The alternate through-bolt (ATB) option for the 9K and 7KC Cylindrical Lock is designed to ease the installation when retrofitting a competitor product. Many commercial grade cylindrical locksets utilize a through-bolt hole spacing of 2 3/4", whereas standard BEST cylindrical locks utilize a 2 35/64" spacing. On the 9K and 7KC, ATB option is only available for locks that use the D rose.
COMPONENTS & KITS
Key In Knob Cylinders
BEST cylindrical locks can be ordered complete with a keyed KIK cylinder provided by BEST. All the necessary components to assure the cylinder and lockset operate together properly will be provided.
Keyed Cylinders Options
When a non-IC lockset is provided with a cylinder, the following three options are available. All three options utilize a “Schlage C” keyway.
• KD – Bag set includes a combinated cylinder, two cut keys, and a selection of tailpieces. Cylinders have a unique combination, which is noted on the keys. Available in either brass (606) or chrome (626).
• KA – Bag set includes a combinated cylinder, two cut keys, and a selection of tail pieces. Cylinders are sold in sets of 4 having the same combination. Combination is noted on the keys. Available in either brass (606) or chrome (626). When ordered with a lock, locks will be packaged 4 to a box to prevent mixing of cylinder codes.
• 0B – Bag set includes a combinated cylinder, two uncut keys, and a selection of tailpieces. All barrels combinated to a zero cut. Keys are uncut and blank. Available in either brass (606) or chrome (626). This option is intended for pinning by the distributor or customer, so the uncut keys can be cut to the proper codes after combinating.
Keyed cylinders may also be purchased from BEST independently from a lockset by specifying the part numbers as shown.
NOTE: When using the cylinders shown (right) with a 9K lock, a B55708 tailpiece is required (not included with cylinder).
SCHRC KIT
The SCHRC adaptation kit allows a 9K cylindrical lock to accept cores in the proprietary large format figure-8 design from Schlage®. This option enables customers to enjoy the benefits of a BEST 9K lockset without having to replace their existing Schlage Removable Core keying system.
The SCHRC adaptation kit contains all the necessary parts to convert a standard 9K interchangeable core chassis to accept cores in the proprietary large format figure-8 design from Schlage® including: lever, tailpiece, washer and spacer.
Please note that double keyed functions require two adaptation kits.
Note: Core not included.
