Backing Rod (Backer Rod)

From Draftsperson.net

An extruded round, closed or open cell, low density compressible flexible foam material inserted into a joint to control sealant depth to create a backstop to:

  • Allow proper sealant tooling
  • Allow proper sealant wetting of the joint surfaces
  • Yield a proper bond breaker between the Backer Rod and sealant

It can also be used as a temporary seal.
