BEST 9K37AB14CS3622 – Frequently Asked Questions

1) What makes this a Grade 1 cylindrical lever lock?
Grade 1 represents the highest ANSI/BHMA commercial rating for lever locks. This Best 9K series lock meets rigorous cycle testing, impact resistance, and latch bolt strength requirements for heavy-duty commercial applications.
2) What door thickness and backset does this lock accommodate?
The Best 9K typically fits standard commercial door thicknesses from 1-3/4" to 2-1/4". Backset options include 2-3/4" and 2-3/8". Verify your specific door measurements against the manufacturer template before ordering.
3) How do I determine the correct handing for installation?
Stand on the side of the door where the hinges are not visible. If the door opens to your right, order right-hand. If it opens to your left, order left-hand. Lever locks require specific handing for proper lever operation.
4) What finish options are available for the Best 9K series?
Best typically offers satin chrome, bright chrome, satin brass, and oil-rubbed bronze finishes. Specific availability depends on the exact model configuration. Check the product specifications for your selected keying option.
5) Can this lock be keyed to match existing Best cylinders?
Yes, Best 9K series locks can be keyed alike or into master key systems. You'll need to specify your existing key code or provide a sample key. Construction keying options are also available for project phases.
6) Is this lock compatible with access control systems?
The Best 9K mechanical lever lock operates independently of electronic access control. For integration with card readers or keypads, consider Best's electrified lock options or electromagnetic locks from our access control category.
7) What's included with the complete lock set?
A complete Best 9K entrance lock includes both lever handles, cylinder, latch assembly, strike plate, and mounting hardware. Keys are included based on your keying specification. Installation template is provided with the lock.
8) What tools are needed for installation?
Standard installation requires a drill, hole saws (2-1/8" for lock body, 1" for cylinder), chisel, screwdriver, and measuring tools. Follow the provided template carefully for precise hole placement and strike alignment.
9) How do I adjust the latch bolt if needed?
The Best 9K latch assembly typically allows backset adjustment during installation. Some models feature field-adjustable latch bolts. Consult the installation instructions for your specific model's adjustment procedures.
10) What's the difference between entrance and office function locks?
Entrance function locks the outside lever when the inside thumbturn is activated. Office function locks both levers when the key turns the outside cylinder. Choose entrance function for most commercial entry doors.
11) Are replacement parts available for Best 9K locks?
Yes, Best manufactures replacement cylinders, lever handles, latch assemblies, and other components for the 9K series. Having the lock's model number and finish helps identify correct replacement parts.
12) Will this lock work in high-moisture environments?
Best 9K locks are designed for interior commercial use. For exterior or high-moisture applications, verify the specific model's environmental ratings and consider appropriate finishes and sealing methods during installation.
