Masterlock 6271 hidden shackle puck lock with stepped backside provides a lot of security for a very reasonable price. Shackle-less padlocks can be used straight on the locking brackets on most trailers and trucks. However, when used in combination with the 770 protective hasp, it becomes a very high security locking system and a serious problem for thieves to by-pass. 6271 has a standard side positioned key-way as opposed to frontal key-way on the American 2500.
Available in keyed different or keyed alike versions.
- Solid steel lock body
- No shackle to cut
- Stepped back
- Side entry key-way
- Rekeyable cylinder
