Abstract
A marking system for cutting an aperture for pipe clearance has a pipe and a pipe stamp. A stamp posterior side has a posterior aperture fluidly connected to an interior cavity. A first rubber stamp projection has an annulus that projects out and away from the stamp anterior surface. A second rubber stamp projection is centrally located on the stamp anterior surface having a general shape of an “X”. The pipe stamp slides over an end of the pipe via the posterior aperture. The first rubber stamp projection and the second rubber stamp projection are placed against a surface for applying a mark for cutting an aperture for pipe clearance.
