These high security leg irons weigh 1.43 kilos and have approximately 30cm of chain between the two 8cm irons which are secured using a 'Yale' type tumbler lock.  This lock is made further secure by a stainless steel cover which is secured with two countersunk posi' screws.  These leg irons are clearly intended for long term use, hence the very high security.

Apologies, we are not allowed to export leg irons outside the European Union.
