Key specifications
 Operation: manual/mechanical caulking gun
 Compatible with standard cartridge formats for silicone and sealants
 Control: hand-operated trigger for regulated extrusion
 Construction: metal and polymer components for durability and reduced weight
 Application: designed for sealants, silicones and construction adhesives
How to use
Insert a standard cartridge into the frame, cut the nozzle to the required bead size and puncture the cartridge seal if present. Hold the applicator so the nozzle is positioned at the joint and squeeze the trigger evenly to extrude material while moving the gun along the seam. Adjust finger pressure to control bead thickness and release the trigger to stop extrusion. Clean any excess material from the nozzle and tool after use to prevent curing on the applicator.
Usage recommendations
Use cartridges rated for the specific adhesive or sealant required for the job, and ensure surfaces are clean and dry before application. For consistent results, practice steady trigger pressure and maintain the nozzle at a constant angle relative to the work surface. Store the applicator in a dry place and remove cured residues promptly to maintain smooth operation.
