High-security round padlock

The Mul-T-Lock TSR50 is a hardened steel padlock with a 7/16 inch boron shackle and patented 006 keyway. It targets fleet managers and facility supervisors who need controlled key duplication for service vans, trailers and building doors. The satin chrome finish resists corrosion in outdoor use.

Upgrade from standard shackle locks

This model replaces basic padlocks that use exposed shackles and unrestricted key blanks. The jump is worth it when bolt-cutter resistance and legal key control are required for high-value cargo or remote sites. Double ball-bearing locking adds pry resistance that simple latch mechanisms lack.

Shackle clearance and cutting resistance

The long boron shackle provides 2 inches of clearance for thick hasps or chain links while resisting cutting attempts. It comfortably secures heavy-duty trailer doors and industrial gates. The round body limits attack surface but offers no shackle-less option like the hockey-puck variant.

Questions about this item

What chain-link or hasp diameter fits the 7/16-inch boron shackle?

The shackle is 7/16 inch thick, so the opening in your chain, hasp or staple must be at least that wide to accept it.

How do I fit the padlock onto a hasp so the double ball-bearing locking engages?

Slide the long shackle through the hasp, push down until you feel two distinct clicks — each click is a ball bearing seating — then turn the key to verify both are locked.

Can I get extra keys cut later, and what authorisation is required?

Only the registered key-card holder can order duplicates; present the card to an authorised Mul-T-Lock service centre to have additional keys cut for the 006 keyway.
