Abstract
Abstract A wooden drop ceiling system is provided which is readily attached to an existing metal T-rail system. A uniquely shaped grooved ceiling tile support is clipped on to the existing T-rail supports by means of U-shaped clips. Cross supports are then clipped on to the cross supports of the T-rails and the basic framework for the wooden ceiling tiles is provided. Transition blocks are also attached to the existing T-rail supports at the intersection of the supports and cross supports. Attractive wooden ceiling tiles of various designs and shapes are then placed into the support grids thus creating an attractive and readily installed wooden drop ceiling.
