Overview of the Combined Systems Blue Box security cover for chain handcuffs | Model 7084


What it is

The Combined Systems Model 7084 Blue Box security cover turns standard chain cuffs into a rigid set for safer control during transport, court moves, and medical escorts. It blocks keyhole access to stop picks or shims while keeping your double lock reachable through exterior slots. MPN Model 7084.


How it works

Load your NIJ-approved chain or hinge cuffs into the Blue Box before placing them on the subject, or fit the cover after application. The internal channel captures the chain and creates a rigid connection between bracelets. For additional security, you may add a padlock to the Blue Box.

The Blue Box has a dark polymer body with a smooth, snag-resistant exterior and a centered panel featuring an oval slot for edge double-lock access. The compact form helps limit wrist rotation and leverage during movements.

Agencies need dependable, repeatable restraint without changing cuff models. The improved Model 7084 accepts all sizes of chain handcuffs and many leg cuffs, weighs only 3.4 ounces, and measures 4.1 by 2.7 by 0.51 inches with a 1.72 by 0.51 inch inside channel. Made in the USA, it is a durable, field-proven solution for frontline teams.

Works great with all speaker wires
Size: 6 pairs
It works pretty well with standard and thin speaker wires. It makes so much easier to plug and unplug speaker wires. Color coded makes it easier for future. Banana plugs are worth. Double screws ensure wires remain securely attached. Screws are bit too tiny and had to run to the store to get one of those fine tip screw driver though.
