Prowler RED Heavy Duty Ankle Cuffs

A pair of sturdy shackles with a good finish and rounded edges, along with their oval shape, make them fit the ankle better despite their weight. I am adding the inner dimensions which are unfortunately missing from the specification. The inner width of the shackles: 73 mm and inner length 87 mm. What might be improved is that the chain could have "swivels" allowing the shackles to rotate without the chain twisting. Possibly, the links could be somewhat thinner/shorter, making the chain more manageable. However, the larger links provide the opportunity to attach other locking devices with chains without issue. It might also be nice if a satin or burlap bag came with it for storing the shackles. A top product for those who want to step up one or two levels from the common ankle shackles of varying quality sold everywhere. Or simply to buy the real deal from the start. Just hope there are new locks available to purchase if something should fail. Good to have four keys. Thumbs up!
