Dripless Caulking Gun

One of the biggest challenges with most caulking guns is stopping cleanly at the end of a bead. This caulking gun is spring-loaded, designed to stop applying pressure to the tube as soon as you release the trigger. You can set the thrust ratio to 12:1 for thick media such as epoxy or silicone, or use the 6:1 setting for media with lower viscosity such as latex sealants.
