About this item
The Arrow HK12 BB 32D is a Grade 1 commercial storeroom cylindrical knob lock from the Arrow HK Series, Arrow's heavy-duty cylindrical platform engineered for the most robust commercial and institutional applications. The full part number breaks down as: HK (HK Series Grade 1 cylindrical knob platform), 12 (function digit for storeroom ANSI F86), BB (ball knob trim), 32D (US32D satin stainless steel finish). The HK12 carries ANSI function F86 (storeroom): the latchbolt is operated by key in the outside knob or by the inside knob; the outside knob is always rigid and cannot be unlocked by push button or thumbturn. This is the standard institutional security function for any door that must be locked from the outside at all times. ANSI/BHMA A156.2 Series 4000 Grade 1 certified. UL and CUL listed for use on 3-hour A-label single swinging fire doors. Backed by Arrow's 10-year warranty. SKU HK12BB32D. In stock under Arrow Knob Locks within Cylindrical Knob Locks in Commercial Locks.
ANSI F86 Storeroom Function Explained
Storeroom (F86) is one of the most-specified ANSI functions in commercial hardware because it is simple, secure, and code-compliant. The outside knob stays rigid until a key turns the cylinder. The key retracts the latch and the knob turns. Release the key and the outside knob locks again automatically. The inside knob is always free for unobstructed egress, which is what makes this an ANSI Grade 1 code-compliant function for occupied rooms. Specify the HK12 on supply and storage closets, IT and server rooms, mechanical and electrical rooms, drug storage in healthcare facilities, evidence rooms, school equipment closets, hospital storerooms, government storerooms, and any commercial opening where every entry needs a key and every exit needs to be free.
Where Arrow Sits in the Commercial Lockset Market
Arrow is part of the ASSA ABLOY family of brands and competes directly with BEST 8K, Schlage AL/ND, Sargent 7-Line/10-Line, Corbin Russwin CL3300, and Yale 5400LN. Arrow's value proposition is the longest standard warranty in the value-tier Grade 1 segment (10 years), full SFIC interchangeability with BEST and Falcon cores, and Schlage C-keyway compatibility for facilities standardizing on Schlage keying. For facility maintenance teams, locksmiths, and spec writers, that means the HK12 drops into existing keying environments without re-pinning the master system or replacing the cylinder hardware. See sister Arrow commercial cylindrical platforms in Arrow Lever Locks for ADA-compliant lever trim configurations.
