What is UTK™ MINI?

The UTK™ Mini is a patented tamping device that is rubber/gel based. The UTK™ Mini comes in packs of four, each device measuring 18” x .5” x 1”( 45cm x 1cm x 2cm) and is designed at .5” (1cm) width to fit the space between the lock and the door jam of most doors. The length of the kit was designed to reach both deadbolt and doorknob simultaneously.


The kit can be used in the construction of a blasting or a pushing charge. The kit was designed with perforations every 6” to give the operator the option to adjust the size of the kit as needed.


Every UTK™ Mini contains 330 rubber on one side and a patented proprietary tamping gel on the other. The UTK™ Gel side comes with a grove along the length of the kit that is designed to fit the explosive seamlessly. The main body of the kit is constructed of raw cardboard which is perforated throughout. These perforations are put in place to reduce the size of fragmentations and to give the end user the ability to modify the kit on the fly.
