Yuil H-1 Belly Chain With Padlock and Universal Black Box Transport Security from South Korea

This is the Yuil H-1. It is a black box system with a belly chain that further restricts the movement of the limbs, while also providing some more limitation of the hands, at the same time limiting access to the keyway to thwart picking the handcuffs open.

This is a South Korean take on a US design Blue Box system, which is very similar. Designed for transport situations where extra restriction is needed during transport to prevent escape or effective attacks of guards. The body of the box is made from plastic or polymer and the slide that goes over the top to hold the box closed and allow locking is made of strong aluminium. The chain is smooth with no harsh welds or any snagging on clothing. The design of the black box also has holes for the double lock, so once fitted, the handcuffs can be tightened to the adequate amount and then be double locked while the box is fully set up and secured. The padlock it comes with only locks on one side, but it uses a ball bearing mechanism which cannot be shimmed, which is a nice feature.

The black box works with several brands (I may do a simple video at some point showing which types of handcuffs fit this Yuil black box in the future). It adds more security to handcuffs. You can also forgo the belly chain and use the padlock directly on the black box, if all you care about is further adding security to the handcuffs but don't need such rigid restriction of the limbs!

A quite flexible system, really.

Also, this is the first appearance of my genuine US prison Bob Barker brand orange jumpsuit. I wanted orange alternatives to my khaki so I can alternate, based on what I want. I have the orange 2-piece scrubs version also, yet to be used. Plain prison clothing like this in Khaki or orange, provide a nice plain background that is bright enough, with no distracting patterns or dark colours that reduce restraint visibility. This way, you can more easily see the handcuffs or leg irons that are being shown in a worn context, compared to back in the day when I wore my usual black clothing. After all, the items are the only star of my videos! Plus the clothing is a good match for the context of the usage of restraints.

Enjoy!
