Introduction

Most customers know the 9K is one of the toughest and safest cylindrical locks on the market. In fact, it's been tested to exceed 10 times the BHMA criteria for Grade 1 levers. It comes in bold, innovative designs. Goes in fast and stands up to everyday use and abuse year after year. To that incredible list of benefits, we're adding a new one.

Because in addition to making the 9K compatible with conventional Key-in-Knob or KIK cylinders, we've made it capable of easily adapting to existing large format interchangeable cores. That's right, people can now change out non-BEST locksets with the 9K—or add 9Ks into the mix without rekeying.

In fact, BEST cylindrical locks can be ordered two ways—configured for use with OEM cylinders from another manufacturer (KIK or Schlage, Sargent, Yale and Corbin Russwin LFIC formats), or complete with a keyed KIK cylinder. In either case, we will provide all the necessary components to assure the cylinder and lockset operate together properly and can be installed quickly.

You may prefer to use BEST locks but have doors already prepared for a different through-bolt configuration. To answer, we offer an alternative through-bolt option that enables the 7KC and 9K to retrofit another common door preparation (2 3/4" or 2 5/8" through-bolt spacing).

Factoring everything in, the BEST 9K could be the one lockset to rule them all.

Alternate Through-Bolt or ATB Options

The alternate through-bolt 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 tailpieces. Cylinders are sold in sets of four, all 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 four 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.
