Abstract: An assembly is disclosed for protecting and supporting a fragile thermometer having a column and an integral flange base. The assembly includes a support base defining a threaded bore for receiving the integral flange base of the thermometer. A bottom cushioning pad is also provided for placement in the bottom of the bore. In addition, a ring-shaped upper cushioning pad is provided for being fitted over the column of the thermometer and against the top surface of the thermometer's flange base. The thermometer is secured to the protective support base with a threaded collar member which receives the thermometer column and is threaded into the threaded bore of the support base which secures the thermometer to the base. An adapter bushing may also be used to attach thermometers having smaller diameter columns to the base.
