Schlage KZ12G40 – Frequently Asked Questions

1) Will the Schlage KZ12G40 shackle fit my Schlage 40 Series padlock?
Yes. The KZ12G40 is built specifically for the Schlage 40 Series padlock family and drops in without modification. It measures 3/8 inch diameter, 4 inch shackle length, and 3/4 inch clearance. If your padlock is from a different Schlage series or another brand, this is not the shackle for it.
2) What size hasp or chain will a 3/8 inch by 4 inch Schlage padlock shackle pass through?
The KZ12G40 gives 3/4 inch of clearance with a 3/8 inch diameter shackle, so the hasp staple, chain link, or gate loop has to accept a 3/8 inch bar and leave no more than about 3/4 inch of opening for the shackle to close. Measure the staple thickness plus the gap on your existing setup before ordering.
3) Can I just replace the shackle on a Schlage 40 Series padlock instead of buying a whole new lock?
That is exactly what the KZ12G40 is for. It is a genuine Schlage replacement shackle that returns a damaged or worn 40 Series padlock to full working condition, so the lock body, cylinder and existing keying stay in service. For a facility with dozens of padlocks keyed into a master system, swapping the shackle keeps the keying intact rather than forcing a rekey.
4) Is the KZ12G40 the padlock itself or just the shackle?
Just the shackle, the U-shaped bar that passes through the hasp. The lock body, cylinder and keys are not part of it. If you need a complete working padlock you have to order a 40 Series padlock; order the KZ12G40 only when the body and cylinder are still good and the shackle is cut, bent or worn.
5) Is the Schlage KZ12G40 shackle rated for outdoor or commercial use?
It is a commercial-grade part. The brass steel construction is specified for corrosion resistance and strength in demanding commercial environments, and Schlage classifies the KZ12G40 as commercial rather than residential. Typical use is building maintenance, warehouse and distribution gates, school grounds equipment, and municipal property.
6) How do I confirm I need a KZ12G40 and not a different length Schlage shackle?
Pull the old shackle and measure three things: the bar diameter, the overall shackle length, and the clear opening between the legs. The KZ12G40 is the 3/8 inch by 4 inch by 3/4 inch version for the 40 Series. A longer clearance shackle on the same series will read the same 3/8 inch diameter but a larger clear opening, so the clearance number is the one that tells them apart.
