Abstract
This invention relates to doors having internal blocking components that reduce or eliminate telegraphing of the outer surface of the door facings. In particular, the invention relates to steel-edge steel doors that have internal solid wood blocks that have one or more integral cantilever beams formed into the blocks to interact with the adjoined oppositely arranged door facings in order to eliminate visually apparent door telegraphing. The blocks are modified to contain notches formed therein to form the cantilever beams.
