In an installation channel to be embedded into a curable construction material, e.g. concrete, having a support profile and preferably an attachment for attaching at least one add-on part to the installation channel, so that the outside of the support profile has a direct connection to the curable construction material at an embedding area, a potential fault block should be large so that large forces can be absorbed by the installation channel.A compressible insert is fastened to the outside of the support profile at the embedding area, so that part of the outside of the support profile is not in direct contact with the curable construction material at the embedding area.
