Dow's most economical foam dispensing gun, the PRO 13 Gun is a great place to get started applying GREAT STUFF PRO products. Enabling precise, pinpoint application control when applying adhesive or when filling, sealing and insulating gaps, cracks, and window and door jambs, the PRO 13 Gun features:
Barbed gun tip, with extended barrel for long-reach applications
Flow control knob for adjustable bead size, from 1/8" to 3" (0.3 cm to 8 cm)
One-hand operation for quick and easy application
Gun tips allow attachment of straw for hard-to-reach areas
Moisture-tight seal between the gun and the can prevents the foam from curing and blocking the dispensing valve, allowing a can to be reused up to one month later.
