Combine the practicality of an extended reach cuff key with super bright LED technology and you get Streamlight's CuffMate. It's improved this year thanks to the addition of a second LED that allows you multi directional lighting for unlocking and double locking of cuffs. Powered by two long lasting lithium batteries, the CuffMate LED flashlight delivers up to 7.5 hours of run time. This streamlight cuff key fits standard cuffs.
