Before using the MEX ensure that your belt is secure and tightened. Tighten the Velcro strap at the top of the TR around your belt. Firmly secure the TR around your thigh with the adjustable strap. Place the paddle of the holster inside the front of the TR and push all the way down. Wrap the front Velcro strap around the holster to secure the holster to the TR. Discontinue using the holster immediately if you experience any discomfort or are unsure as to the proper way in which the holster should be worn. Prior to using the holster with a loaded firearm, ensure that you have carefully read and understood the operating and safety instructions that apply to the specific holster or magazine pouch used with the TR.
Attachment of your holster/pouch to the MEX is done by a simple Phillips screw.
MEX allows for numerous choices of height for your holster/pouch, by a simple manual turn of a cogwheel/gear located at the back of the MEX.
The MEX fits three different belt widths, 1.25", 1.5" and 2.25".
