BEST 9K30L14DSTK626 – Frequently Asked Questions

1) What is a Grade 1 cylindrical lever lock and where is it used?
Grade 1 represents the highest ANSI/BHMA security and durability rating for commercial door hardware. These locks withstand heavy use in high-traffic applications like offices, schools, and healthcare facilities. The cylindrical design mounts through standard door prep holes.
2) What does "privacy" function mean on this lever lock?
Privacy function locks from the inside using a push button or turn mechanism. There's no key cylinder on either side. Common for restrooms, private offices, and conference rooms where occupants need temporary privacy but emergency access may be needed.
3) What door thickness and backset does this lock accommodate?
Most cylindrical lever locksets fit 1-3/8" to 1-3/4" thick doors with standard 2-3/8" or 2-3/4" backset. Verify your door thickness and measure from door edge to center of existing hole before ordering. Check manufacturer specifications for exact compatibility.
4) How do I determine left or right hand orientation?
Stand on the side where the door opens toward you. If hinges are on your left, it's left-hand. If hinges are on your right, it's right-hand. Most cylindrical locks are reversible by rotating the latch mechanism during installation.
5) What finishes are typically available for commercial lever locks?
Common finishes include satin chrome, polished chrome, satin stainless steel, oil-rubbed bronze, and bright brass. Satin finishes hide fingerprints better in high-touch areas. Match existing hardware throughout your facility for consistent appearance.
6) Does this lock meet ADA compliance requirements?
Lever handles typically meet ADA requirements for ease of operation compared to knobs. Verify the specific model meets 5-pound maximum operating force and other accessibility standards if ADA compliance is required for your application.
7) What's included with the lockset package?
Complete lockset includes both lever handles, latch mechanism, strike plate, and mounting screws. Installation template and instructions are typically provided. Some models include dust covers for pre-installation protection.
8) Can this be installed on existing door prep?
If your door has standard cylindrical lock prep (2-1/8" cross bore, 1" edge bore), installation should be straightforward. Different manufacturers may have slight variations in mounting requirements. Check the installation template against your existing holes.
9) How do I maintain and adjust cylindrical lever locks?
Regular cleaning and light lubrication of moving parts extends lock life. If levers sag over time, check mounting screws for tightness. Privacy function mechanisms may need periodic cleaning to ensure smooth operation.
10) What's the difference between cylindrical and mortise locks?
Cylindrical locks install through cross-bore holes and are more common in commercial applications. Mortise locks require a pocket cut into the door edge but offer more functions and higher security. Cylindrical Grade 1 locks provide excellent security for most applications.
11) Can I get emergency override capability with privacy locks?
Many privacy locks include emergency override features like small hole for emergency key or coin slot on outside lever. This allows facility managers to unlock doors if needed while maintaining normal privacy function for occupants.
