The premium lock for quality, performance, and security.

Building on BEST’s legacy of innovation, the 9K series cylindrical lock combines top-quality materials and exceptional craftsmanship into a tough, dependable, long-lasting security solution. We designed the 9K series to be low maintenance, easy to install, durable, and secure. And our range of available styles and finishes ensures that the 9K delivers design aesthetics to match a wide variety of applications.

FEATURES

  1. For versatile applications, lever by knob trim variations are available.
  2. Rose locking pin and rose assembly design offers great torque resistance. It prevents the locking pin from twisting, bending, or breaking under attack.
  3. The innovative design of the slotted key release cam and locking lug assembly creates maximum attack resistance. Even though damaged, the lock still allows key access. In addition, the lever is fully functional from the inside. The hub-mounted torsion spring and strong retractor springs help prevent lever sag and offer a smooth and snappy operation.
  4. Strong through-bolt mounting studs increase torque resistance. The heavy rose liner material is highly attacked resistant.
  5. Strong retractor springs provide resistance to lever sag.
  6. Zinc hubs with a shrouded locking lug, guaranteeing higher quality and increased torque resistance.
  7. The outside lever sleeve is a seamless one-piece construction made of a hardened steel alloy that provides additional reinforcement in
    the locking lug slot.
  8. Lost Motion feature available allowing 45º lever rotation in either direction without engaging retractor assembly.
  9. Interchangeable core allows for quick re-keying and customized master keying.

BEST 9K30N15DS3626 – Frequently Asked Questions

1) What is a passage function lever lock and where is it used?
A passage function lever lock allows free operation of both levers without requiring a key or locking mechanism. It's commonly used for hallways, closets, and interior doors where privacy or security locking isn't needed but lever operation is preferred over knobs.
2) What does Grade 1 certification mean for cylindrical lever locks?
Grade 1 is the highest ANSI/BHMA rating for cylindrical locks. It requires 800,000 cycle testing, 300 lbf applied force resistance, and meets commercial heavy-duty specifications. Grade 1 locks provide maximum durability for high-traffic applications.
3) What door thicknesses does this cylindrical lever lock accommodate?
Most Grade 1 cylindrical lever locks accommodate standard door thicknesses from 1-3/8" to 1-3/4". Some models adjust to 2" thick doors. Always verify compatibility with your specific door thickness and check manufacturer specifications for exact ranges.
4) Is this lever lock handed or universal for installation?
Most cylindrical passage lever locks are non-handed and can be installed on right-hand or left-hand doors. The lever returns to horizontal position and operates freely from both sides regardless of door swing direction.
5) What backset does this lock require and is it adjustable?
Standard cylindrical locks typically use 2-3/8" backset, with many models offering adjustable backset to accommodate 2-3/4" spacing. Check the specific model specifications and ensure your door preparation matches the required backset measurement.
6) What finish options are available for Grade 1 lever locks?
Commercial grade lever locks commonly come in satin chrome, polished chrome, satin stainless steel, oil-rubbed bronze, and brass finishes. Grade 1 locks feature durable finish coatings that resist wear and corrosion in high-use environments.
7) Can this passage lock be converted to other functions later?
Passage function locks cannot typically be converted to keyed or privacy functions. The internal mechanism is specifically designed for free passage operation. If locking capability is needed, select a different function from the same lock series.
8) What hole preparation is needed for cylindrical lever lock installation?
Standard preparation requires a 2-1/8" diameter hole through the door face and 1" diameter hole in the door edge for the latch. Most locks include paper templates for precise hole placement. Use proper hole saws for clean cuts.
9) How do I adjust lever spring tension if it becomes loose?
Lever spring tension is typically factory-set and not field-adjustable on most cylindrical locks. If levers don't return to horizontal position properly, check for worn springs or damaged internal components that may require lock replacement or professional service.
10) What maintenance does a Grade 1 passage lever lock require?
Regular cleaning with mild soap and water maintains finish appearance. Periodically lubricate the latch mechanism with graphite or light machine oil. Avoid petroleum-based lubricants. Check mounting screws annually in high-traffic applications.
11) Are there ADA compliant options in Grade 1 cylindrical lever locks?
Yes, most lever-style locks meet ADA requirements when properly installed. Levers must operate with 5 lbf maximum force and return to within 1.5" of the door face. Verify specific model ADA compliance and mounting height requirements.
