Holmatro Door Blaster HDB 90 ST

Door opener for extremely fast door breaching. Designed for quiet and remote operation.


Faster than ever, quiet remote operation
The Holmatro Door Blaster is the latest innovation in breaching multiple lock, inward opening doors. As fast as explosives, without the flying debris. And hardly any sound until the moment the door flies open. Installing the tool is quick and easy: simply press a button on the door opener with your thumb to clamp it in the door frame. Remote operation is a big plus too. It allows you to step away from the door and activate the door opener’s pushing and quick-release functions from a distance. Thanks to its compact dimensions and low weight you can carry, install and operate the system by yourself. This saves manpower and allows your team members to focus on other operational tasks. Add to this extremely fast and quiet operation and you have a groundbreaking solution for forcible entry!
