Used before re-caulking, this tool is for removing caulk or other sealants from a seam. A razor knife should be used to free the caulk from the sides of the seam. Our Reefing Hook is specially designed and constructed for long service life, and ease and speed of operation. You can remove most of the caulking, leaving minimal material for final hand sanding - using the TDS Seam Sander. TDS Reefing Hook is made to be a fine quality tool with hand comfort in mind. Different sizes can be made to order.
