Bulk Applicator Gun
The Bulk Applicator Gun delivers high-volume compound placement with clean, consistent flow. A lightweight drawn-aluminum barrel, adjustable feed screw, and ergonomic grip reduce hand fatigue on long production runs. Quick reloads pair perfectly with the Bulk Dispenser Plate for mess-free changeovers on jobs that need thousands of tube-equivalents. Ideal for sealing, damping, and drywall finishing on pro jobs.

- Precision Metering Control: Trigger and tip options support accurate bead sizing, reducing material waste and ensuring the right amount lands exactly where it should.
- Fast, Clean Reloads: Follower plate pulls compound directly from 5-gallon pails without pulling air.
- Rugged Yet Light: Drawn-aluminum body withstands daily jobsite use.
- Ergonomic Balance: Comfortable grip reduces fatigue over extended shifts.
- Material Versatility: Green Glue, sealants, and joint-compound compatible.
- Cleaner Workflow, Less Mess: Bulk loading and controlled discharge keep compound off floors, tools, and work areas.
