Plan B


Developed by 4TAC5 the ‘Plan B’ is a Fast Track Counter Custody Kit that can be donned or removed in seconds so it can be carried & concealed
on your person, regardless of what you are wearing. It is also very comfortable to wear so you’ll easily forget that you’re wearing it (passive).
Full access to the tools is possible if you are restrained to the front or rear and need to put ‘Plan B’ into action!

We recommend that you carry inside your underwear with the Go-Tube positioned just above your groin and shim installed at the rear on the silicone retainers.
If you are restrained to the rear access to the Go-Tube is possible by pulling on the shock-cord to move it from the front to the rear.
The contents of the Go-Tube can be accessed by pulling off the round end cap with your finger nails, or you can leave the cable-tie of the Friction
Saw outside of the cap – simply pull on the cable-tie to remove the cap.


– GO-TUBE IWB STRAP featuring shock-cord strap for inside waistband carry & concealment, hanger cap with heat shrink retention and end cap
reinforced with an acrylic disc. It is lightweight, airtight, waterproof/mildew-proof with silent operation.

– UBER GULAG SHIM with stainless steel split ring installed on shock-cord waist strap with silicon retainers
for access when restrained to the front or rear.

– T200 HIGH SPEED FRICTION SAW developed by the 4TAC5 Mobile Training Team, SERE and CAC Instructors.
The overall length, size of the foot-loops and the addition of a plastic feeder allow for this tool to be quickly deployed and used
immediately to defeat non-metallic restraints should you be restrained to the front or rear.

– SAD-TOOL (Special Activities Development Tool) designed to defeat various handcuffs and restraints
from around the world. Can also be used to open basic padlocks.

– MICRO STRIKER BEAD TUNGSTEN CARBIDE (installed on shock-cord waist strap). Measuring just 6.75mm x 3.25mm this is our smallest glass beaker
for tempered glass windows. Using the Mohs scale, which is used to test hardness, the score achieved by tungsten carbide is 9.
To put this into context, the only thing that has a higher score than tungsten carbide is a diamond, which manages to score a rating of 10.
As the old saying goes it takes a diamond to cut a diamond but it also takes a diamond to cut tungsten carbide. With a mineral hardeness of 9.0 MOHS
the MSB-TC will break tempered glass windows with very little effort.

– MICRO LIGHT STICK (x 2) 1.5 inch mini chemical light sticks will glow green for 4hrs once activated.
