Q: What is the 8K and when was it first offered?
A: The 8K is a grade 1 cylindrical knob set that was designed and launched in America in the 1980s. There are no lever options for the 8K. The 8K cylindrical knob set and the 9K cylindrical lever set share the same latch and retractor assembly.
Q: What materials are used to manufacture the 8K?
A: All 8Ks are constructed of steel or brass, which contributes
to the overall strength and durability of the lock. They do not contain weaker metals, like zinc or aluminum, commonly found in other cylindrical knob sets.
Q: What door thickness range can the 8K accomodate?
A: The 8K comes preset from the factory to fit 1 ¾" thick doors but can be field adjusted to fit 1 3/8" – 2" thick doors. Additionally, the lock assembly can be modified to accommodate doors up to 3" thick using a special rose trim (E).
Q: How is the BEST 8K knob made?
A: The 8K knob's structure is machined from one solid piece of brass into one solid lock unit, opposed to having multiple parts formed, stamped or pressed and then joined into a single unit. This single machined unit makes the 8K knob more resistant to wear and tear, dings and dents and provides
greater overall structural integrity to the device.
Q: What functions are offered for the 8K?
A: The 8K is available in 7 single key functions (i.e., entrance, storeroom, service station, classroom, dormitory, UA & hotel), 5 double-keyed functions (i.e., corridor, storeroom, intruder, communicating & institutional), and 6 keyless functions (i.e., passage, exit, privacy, patio, single dummy trim & double
dummy trim).
Q: What cores must be used for the 8K?
A: The 8K accepts any SFIC (Small Format Interchangeable Core).
Q: Do you have to specify hand when ordering the 8K?
A: The 8K has a rotating knob face. One can simply pull the core out and spin the base to change the handing. This ensures the core does not appear upside down and eliminates
the necessity to order a right-handed or left-handed lock. (Please refer to the image on above.)
Q: What knob styles are offered for the 8K?
Q: What rose styles are offered for the 8K?
A: The 8K is available in 4 rose styles.
A: 3-3/8" concave
C: 2-9/16" concave
D: 3-3/8 convex
E: 3-3/8" concave
Q: What finish are offered for the 8K?
A: The 8K is available in 10 finishes: Standard (626, 690, 622), Satin (606, 612, 613, 619), and Bright (605, 611, 625, 618). An anti-microbial coating can be added to these finishes. Also note that 613 is a living finish that ages over time.
Q: How hard is it to install the 8K?
A: The 8K is very easy to install and can be done in a few minutes or less once the door is prepped. The 8K fits the common cylindrical (161) door prep. The installation requires two screws which are used for the latch only. Once the latch is installed, one must simply slide the chassis through the 2 1/8" diameter hole and snap the inside knob onto the inside
spindle.
Q: What is the difference between interchangeable
cores (IC) and non-interchangeable cores (Non-IC)?
A: Interchangeable cores can be installed and removed from the outside through the use of a control key. Noninterchangeable cores must be installed and removed by first taking the lever off. Interchangeable cores have a figure 8 design whereas non-interchangeable cores have a single hole design.
Q: What is the average lead time for an 8K?
A: The average lead time for an 8K is less than 2 weeks.
Q: What is the warranty on the 8K?
A: The 8K has a 3 year warranty.
