Great Stuff's™ most economical foam-dispensing gun, the PRO Gun 13 is a great place to get started when applying Great Stuff Pro™ products. It enables precise, pinpoint application control when applying adhesive and filling, sealing and insulating gaps, cracks and window and door jambs. All PRO Series foam-dispensing guns are designed to create an air- and moisture-tight seal between the gun and the can. Each PRO gun features a flow control mechanism that permits dispensing a bead size from 1/8" to 3" precisely where needed.
