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 create 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. Heavy rose liner material is highly attack 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 masterkeying.

BEST 9K37D-14-D-S3-626 – Frequently Asked Questions

1) What is a storeroom function lever lock and how does it work?
A storeroom function lock keeps the outside lever locked at all times. Entry requires a key from the outside. The inside lever always operates freely for egress. This function is ideal for storage areas, utility rooms, and spaces requiring controlled access.
2) What door types and thicknesses work with this cylindrical lever lock?
This lock fits standard 1-3/8" to 1-3/4" thick doors. Compatible with wood, metal, and composite doors. Door must have 2-1/8" bore hole and 1" edge bore. Verify door weight capacity and manufacturer specifications before installation.
3) How do I determine the correct handing for this lever lock?
Stand on the side where the door opens toward you. If hinges are on the right, it's right-handed. If hinges are on the left, it's left-handed. Most cylindrical locks are reversible and can be configured during installation.
4) What finishes are typically available for commercial lever locks?
Common finishes include satin chrome, bright chrome, satin stainless steel, and oil-rubbed bronze. Some models offer painted finishes. Verify specific finish availability with product specifications as options vary by manufacturer and model.
5) What does Grade 1 certification mean for commercial door locks?
Grade 1 is the highest ANSI/BHMA standard for commercial locks. It requires 800,000 cycle testing, higher torque resistance, and superior security features. Grade 1 locks meet heavy-duty commercial applications and high-traffic areas.
6) Can this lock be keyed to match existing building keys?
Yes, most commercial cylindrical locks can be keyed alike or keyed different. Master keying systems are also possible. Consult with a locksmith or key management professional to coordinate with existing building key systems.
7) What replacement parts are commonly needed for cylindrical lever locks?
Common replacement parts include lever handles, lock cylinders, latch assemblies, and strike plates. Springs, screws, and internal mechanism components may also need replacement over time. Keep model numbers for accurate parts identification.
8) What are the basic installation requirements for this type of lock?
Installation requires 2-1/8" hole saw for face bore and 1" spade bit for edge bore. Standard backset is typically 2-3/4". Door frame must be prepared for strike plate. Follow manufacturer template for precise measurements and alignment.
9) How do I maintain and adjust cylindrical lever locks?
Regular cleaning with mild soap prevents dirt buildup. Lubricate moving parts with graphite or appropriate lock lubricant annually. Check lever tightness and strike plate alignment periodically. Avoid over-tightening screws which can bind internal mechanisms.
10) What other lock functions work similarly to storeroom locks?
Office function locks operate similarly but can be unlocked from outside when key is used. Classroom function locks allow outside lever to be locked or unlocked. Entry function locks provide both keyed entry and inside locking capability.
11) How do environmental conditions affect lock performance?
Exterior applications require weatherproof ratings and corrosion-resistant finishes. High-humidity areas may need stainless steel components. Temperature extremes can affect lubricants and metal expansion. Choose appropriate grade and finish for specific environmental conditions.
12) What measurements should I verify before ordering a replacement lock?
Measure door thickness, backset distance from door edge to center of bore hole, and existing hole sizes. Note current lever style and finish. Check if lock is handed or reversible. Verify strike plate dimensions and door frame preparation.
