Master Lock 293LJS6127 – Frequently Asked Questions

1) Which Master Lock padlocks does the 293LJS6127 shackle fit?
The 293LJS6127 boron shackle is built for Master Lock 6127, 6427, and 6627 Pro Series padlocks. It drops into those bodies as a direct replacement with no modification. If your padlock body is a different Pro Series number, this is not the shackle for it.
2) How tall is the 293LJS6127 shackle, and will it reach through a thicker hasp or a chain?
Shackle height is 2-3/8 inches, which is the longer clearance option for Pro Series bodies. That extra vertical opening is what lets it pass through thicker hasps, gate chain links, and stacked fittings that a short shackle will not clear. Measure the combined thickness of what you are locking through before ordering.
3) My Pro Series padlock shackle was cut. Can I rebuild the lock instead of buying a new padlock?
Yes, if the body and cylinder are sound. The 293LJS6127 is the genuine OEM service shackle for 6127, 6427, and 6627 bodies, so swapping it restores the lock's original security performance rather than leaving you with a compromised unit. For facilities running a keyed-alike system this is usually the cheaper path, since you keep the existing cylinder and keying instead of re-keying a new padlock into the system.
4) Is the replacement shackle hardened, or just plain steel?
Hardened boron alloy, the same material spec Master Lock uses on the factory-installed Pro Series shackle. That is what gives it the cut and saw resistance; a plain steel aftermarket shackle in a Pro Series body downgrades the whole lock to the weakest part.
5) Do I get a cylinder or keys with the 293LJS6127?
No. The 293LJS6127 is the shackle only, sold as a replacement service part. The padlock body, cylinder, and keys stay as they are, which is exactly why maintenance departments use it, the existing keying is untouched. If you need cylinder or key service, order those parts separately.
6) I manage a lot of padlocks. Can I stock this shackle across a mixed fleet of Master Lock padlocks?
Only for the 6127, 6427, and 6627 Pro Series bodies. It is not a universal shackle. If your property runs several Pro Series models, keep shackles stocked by body number, and note that this one is the 2-3/8 inch tall profile, so a lock originally fitted with a shorter shackle will gain clearance after the swap.
7) Is this shackle suitable for commercial and industrial use, or is it a homeowner part?
It is a commercial-rated part. Typical uses are gate and door security on commercial property, warehouse and storage access, construction equipment, fleet security, and industrial lockout/tagout programs.
