Multifunction Retractable Buckle (MRB) System

Tired of losing keys, grenade pins or other small accessories? This product is for you! The MRB system or Multifunction Retractable Buckle system has been designed to enable the user to use the item (keys for example) whilst they still remain attached to them to prevent loss. The system can be used with Molle, belt or clip attachment to attach it to your gear or person and the other end features a heavy-duty retractable line that also had a disconnector clip (if you did need to remove the item to give it to another member of your team for example). Once you have used the item and released it the strong retention system will snap the item back to the MRB and retain it there until its needed. A good application can be for grenade pins – once you have deployed the grenade the MRB will keep hold of the pins until you are ready to rearm your device. the stretch cord means that you would be able to have the system attached when the device is still inside the pouch and it would not prevent you from removing the item so you can throw it!

Included in the box:

  • 1x Small Screwdriver
  • 1x Velcro Webbing Strap
  • 1x Plastic Accessory Clip
  • 1x Split Ring and Pin
  • 1x Retractable buckle assembly with metal HHK style clip
