Hardware

The right hardware for the right door!

HardwareIn most cases, the type of hardware required on any door is a function of its overall weight and the frequency of its operation. In fact, the hardware is the weight bearing element of the door and thus, must be chosen with strict capacity limitations.

Acceptable safety factors must be kept in mind. Thermostop Inc. has provided you with a chart to simplify this selection task. It must be noted that the following chart corresponds to door weights equivalent to the ThermostopTM doors using standard 26 gauge steel sheeting or the ThermostopTM AL-2000 aluminum doors using standard single glazing, standard double acrylic or polycarbonate.
