Schlage KZ12D20 – Frequently Asked Questions

1) Will the Schlage KZ12D20 shackle fit any Schlage padlock, or only the 20 Series?
Only the 20 Series. The KZ12D20 is built as an exact-fit shackle for Schlage 20 Series padlocks, so it drops into that lock body and no other. If the lock you're repairing is a different Schlage padlock series, this shackle is the wrong part and you need the shackle matched to that series.
2) What size is the KZ12D20 padlock shackle, and how much clearance does it give me for a hasp or chain?
The shackle is 5/16 inch diameter, with 1-1/2 inch vertical length and 3/4 inch horizontal clearance. That 3/4 inch opening is what limits what you can pass through it, so measure the hasp staple, chain link, or cable you're locking before ordering. A heavier chain or a thick hasp won't clear a 3/4 inch span.
3) Can I replace just the shackle on a worn Schlage 20 Series padlock instead of buying a new lock?
Yes, that's the point of the KZ12D20. It's a drop-in replacement shackle that restores padlock function without swapping the lock body, so a keyed-alike padlock stays on its existing key and you keep the same lock in service. Practical where a bent or cut shackle is the only failure and the cylinder and body are sound.
4) Is the KZ12D20 shackle rated for commercial use or is it a residential-grade part?
It's a commercial part. Schlage classifies the KZ12D20 as commercial rather than residential, and it's supplied as a genuine Schlage replacement component for 20 Series padlocks used in offices, schools, healthcare, warehouses, municipal buildings, retail, and multi-tenant residential properties.
5) I manage a property with dozens of Schlage padlocks. Can I stock this one shackle for all of them?
Only for the 20 Series locks in the fleet. The KZ12D20 is dimensioned specifically at 5/16 inch diameter with 1-1/2 inch vertical and 3/4 inch horizontal clearance for that series, so if your padlocks are mixed across series you'll need a shackle per series rather than one stocking item. Where the fleet is standardized on 20 Series, one part number covers every lock.
6) Does the KZ12D20 come with a key or cylinder?
No. The KZ12D20 is the shackle alone, a replacement component for the 20 Series padlock assembly. The cylinder, key, and lock body stay as they are, which is why the lock keeps working on its existing key after the swap.
7) What is the KZ12D20 made of, and will it hold up outdoors?
Brass steel construction, which Schlage specifies for corrosion resistance in demanding commercial environments. That makes it a reasonable choice for exposed gates, yard enclosures, and warehouse dock hardware where a plain steel shackle would rust.
