Quickly set foam backer rods (not included) in caulk joints at a consistent depth without puncturing them.

Tools with a threaded handle are small enough to be kept in your tool kit, making them good for quick jobs with short runs of backer rod. To make them more ergonomic, add a pole handle so you can stand while installing a backer rod on the ground.

Tools with a backer rod holder are ideal for inserting long runs of backer rod quickly. They keep your backer rod organized and positioned, so you can press it into place with just one pass.
