Each section has about 1/8-1/4 inch of mesh that extends over each end so that the sections can overlap each other slightly. If there is an issue where the mesh doesn’t lay flat over the adjoining piece of mesh, first try to flatten the ends of the mesh using a pair of pliers, or you can put a sheet metal screw between both pieces of mesh to fasten them down. Please avoid pushing down too hard so not to cause an indent or pocket in the mesh.
