Recently there may be many specifications such as when opening and closing the floor manhole which began to deform. As long as I can not get enough power unless it is about this size. If that happens, the price goes up, but here as well, I decided to purchase because the price is not so expensive. Since there are few specifications other than the above, strength and weight are satisfied.
For disaster prevention emergency use, I will place it in the room on the second floor. As it is using a bar size of 60 cm in size which is easy to use separately on a do-it-yourself carpent etc, probably will not use everyday. This bar of 90 cm is unexpectedly light and easy to hold, I think that it will be useful for breaking open the door in emergency.
