SFB 21 Round Lock specialty padlock with 21mm rotating Hardened Steel Shaft.

Available keyed different or keyed alike (can be keyed alike to the DIB U lock series)

This spinning padlock has a perfect fit combined with the 16mm Protector range of chains. Locked into the base, both parts rotate freely making it extremely difficult to attack. 
This lock can also be used as a motorcycle disc lock if there is an opening of at least 21mm but not larger than 40mm (1-9/16"). 
Next to being impervious to physical attacks, the high security floating disc key-way makes this lock extremely difficult to pick. 

  • 21mm - 0.82" heavy steel shaft.
  • Rotating parts provide no leverage.
  • Anti-grip slanted and rounded sides.
  • Chrome finish
  • 3 high security keys.
  • Dust and water cover.

Shackle: 21mm  -  0.82"
Body: 40mm 1-9/16" round
Clearance: 16mm  7/16"
Total height (including cap) 81mm 3-3/16"

A version of this lock was previously available under the name Untouchable Lock.

Exceptional Chain Lock

There is an excellent 4 minute video on YouTube about this lock and another 4 minute video about the Pragmasis Protector Chains it fits perfectly. I am extremely happy with the two RL21 RoundLocks I have! This lock has achieved "SOLD SECURE MOTORCYCLE GOLD" accreditation in Europe and is ideally suited to use with the serious security Pragmasis Protector Chains (13mm, 16mm). The RoundLock fits snugly against the edges of the chain`s links, protecting it, making it very difficult to attack. When attacked (in a YouTube video) with a sledgehammer, the lock merely deformed (the shape of the lock itself makes it very difficult to hit squarely). It`s inaccessible with bolt croppers, and is so thick that an angle grinder attack causes little damage – in fact the chain is the easier option for a crook to attack. I think it’s an incredible chain lock! Check out the YouTube videos.
