The PRO Gun 14 XL has the maximum amount of reach you need for applying adhesive and filling, sealing and insulating gaps, cracks and window and doorjambs. It enables precise, pinpoint application control when applying GREAT STUFF PRO™ products. 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. The ability to restart combined with pinpoint control allows for maximum foam yield and minimal waste.

  • Lightweight, high-strength aluminum body offers better comfort and control
