Schlage KS23F2300 Padlock, 5/16" Dia. Shackle, 2" Clearance

The Schlage KS23F2300 is a commercial-grade brass padlock from the Schlage 2300 Traditional Series. Hardened alloy steel shackle, double deadbolt locking mechanism, 6-pin solid brass cylinder on the trusted Schlage C keyway. It's the padlock locksmiths and facility managers reach for when they need something that keys into an existing Schlage masterkey system while holding up to outdoor exposure and daily commercial use. Meets or exceeds ASTM standards for shackle strength, shackle cutting resistance, and corrosion resistance. 

What Is the Schlage KS23F2300

The KS23F2300 is part of the Schlage 2300 Traditional Series, the commercial brass padlock line that's been a go-to spec for decades in schools, municipal facilities, utility companies, storage operations, and any building that already runs on Schlage C keyway hardware. The "F" suffix in KS23F2300 identifies this specific shackle configuration: 5/16" diameter, 2" clearance between the shackle and the body (also called shackle height). That 2" clearance is the middle size in the 2300 lineup, long enough to fit through most gate hasps, locker hinges, fence latches, and equipment lockouts, without being so long that it's easy to attack with bolt cutters. The brass body resists corrosion, and the hardened alloy steel shackle resists cutting, sawing, and leverage attacks.

Schlage C Keyway and Keying Options

The Schlage C keyway is the most widely specified commercial keyway in North America, which is exactly why so many facility managers choose 2300 Series padlocks. If your building already runs Schlage C on doors, cabinets, or cores, the KS23F2300 keys right into that existing system. Order it Keyed Different (KD) for independent keys on each lock, Keyed Alike (KA) when you want one key to open a group of padlocks, or Masterkeyed (MK) to fit the lock into a hierarchical keying schedule for a school, property management portfolio, or utility company. Two cut Schlage-branded nickel silver keys ship with each lock, and the solid brass 6-pin cylinder is pinned 5 standard, leaving one chamber for masterkeying.

Use Cases for the KS23F2300 Brass Padlock

The 2" shackle clearance makes the KS23F2300 versatile across a wide range of commercial and institutional applications: fence gates and chain link enclosures, storage yards, utility meter boxes, electrical panels, trailer doors, school lockers and athletic equipment, HVAC roof access hatches, warehouse cages, construction site toolboxes, and municipal park equipment. The brass body handles outdoor weather better than plain steel, and the ASTM corrosion-resistance rating means it holds up in coastal, industrial, and high-humidity environments where cheap padlocks rust out within a season.
