Product Description
The Arrow MK12 is a Grade 2 storeroom function cylindrical knob — outside knob always rigid, key retracts latchbolt. Inside knob always free. For supply rooms and storage. The MK series delivers commercial-grade quality at a price point that makes sense for apartment buildings and light commercial projects where Grade 1 is overkill.
Keyway: This lock ships with the standard Arrow keyway (AR1) — keyed to the Arrow factory keyway, not Schlage. If you need a Schlage C (SC1) keyway to match an existing Schlage keying system, contact us before ordering and we will quote the Schlage C variant (MK12-BD-26D-CS).
BD knob in 626 satin chrome. Standard 2-1/8" bore prep, 2-3/4" backset. Fits 1-3/8" to 1-3/4" doors. Non-handed. BHMA A156.2 Series 4000, Grade 2, UL listed. Note: knob hardware does not meet ADA — for accessibility compliance, use the RL lever series instead.
Lock Depot sells brand new Arrow Lock products with the full manufacturer warranty.
