After a break, we have secured all the windows and doors of our house with 2 FTS88 each that are supposed to withstand any pressure about 800 kp. Fortunately, (almost) all to order the same castle, so we only need 1 key for all FTS88. The last 2 we have assembled for 2 very small window was broken by the neighbor and of which we would not have thought that one gets through there. Installation in wooden windows is simple, albeit sweaty.
