PDQ SF126 Passage, Grade 2 Standard Duty Cylindrical Lock

The PDQ SF126 is a Grade 2 standard-duty cylindrical lock in the passage function, part of PDQ's SF Series. Passage means exactly what it sounds like: the latchbolt is operated by the lever from either side at all times, with no locking. It's the lock for doors that need a latch and a lever but never need to lock, like corridors, closets, and pass-through doors in apartments, offices, and light commercial spaces. If you're searching the SF126, SF-126, or SF 126, this is the passage version of the SF Series, built to give multi-family and light commercial projects reliable hardware without overspending.

Why a cylindrical passage lock beats a tubular one

The SF Series is built around one practical advantage: it's a cylindrical lock, not a tubular lock. That matters more than it sounds. A cylindrical lock has a heavier, more robust chassis than the tubular locks commonly sold for budget projects, so it holds up better to daily use and abuse. For multi-family housing, senior living, student housing, and offices, where interior doors get used constantly, that extra durability is the difference between hardware that lasts and hardware you're replacing in a few years. The SF126 gives you that cylindrical strength in the simplest, no-lock passage function.

It also fits standard 160 and 161 door prep and retrofits all major manufacturers' preps, so it drops onto existing doors without new drilling, and it needs no additional thru-bolt.

Why specify the PDQ SF Series

PDQ built the SF Series for a clear job: tough, reliable Grade 2 performance at a competitive price for projects where a cylindrical lock is the right call but a heavy-duty Grade 1 isn't needed. The smart part for a multi-unit project is that the SF shares common levers and finishes with PDQ's SD cylindrical and CL interconnected locks. That lets you put an interconnected or entry lock on the unit door and the SF126 passage on the interior doors, and have everything match for a uniform look across the whole building. The Schlage C compatible keyway and interchangeable-core option also let it slot into an existing key system instead of forcing a separate one.

One thing to confirm before ordering: the SF126 is the passage (non-locking) function. If a door needs to lock, you want the privacy, entrance, or storeroom function in the same SF Series instead, so match the function to what each door actually does.
