Foam Gun Drel CON-LGF-0103 — handheld applicator for polyurethane mounting foam

The Drel CON-LGF-0103 foam gun is a handheld applicator designed to dispense polyurethane mounting foam from standard cans. It features a pistol-style grip and trigger mechanism that allow one-handed control over foam output, enabling precise application for filling gaps, insulating joints, and sealing around windows and doors. The gun connects to common threaded foam cartridges and is suitable for both professional contractors and DIY users who need a controlled, steady flow of foam for construction and renovation tasks.

Advantages

The gun provides improved accuracy and reduced waste compared with direct can application, allowing fine adjustment of foam flow via the trigger. Its ergonomic pistol grip and balanced weight distribution support comfortable, extended use. Durable materials and a threaded connection designed for common cartridges ensure compatibility and reliable performance. The tool also permits cleaner application and easier finishing of foam beads.

Suitable for

• Filling cracks and gaps in walls and foundations
• Insulating and sealing window and door frames
• Installing and fixing insulation panels
• Soundproofing joins and cavities
• General sealing and mounting work in renovation projects

Key specifications

• Handheld, pistol-style applicator with trigger control for one-handed operation
• Threaded connection compatible with standard polyurethane foam cartridges
• Material: corrosion-resistant metal and reinforced plastic components
• Adjustable foam flow via trigger for precise bead control
• Suitable for professional and DIY use in construction and renovation

How to use

Attach a compatible polyurethane foam cartridge to the threaded connection following the cartridge manufacturer’s instructions. Hold the pistol grip and depress the trigger gently to start dispensing foam; modulate trigger pressure to control flow and bead size. Apply foam steadily to the joint or cavity, working from one end to the other, and avoid overfilling. After dispensing, release the trigger and, if needed, wipe the nozzle. Clean the gun according to the foam manufacturer's guidelines to prevent hardened residue; many workflows recommend using a dedicated foam cleaner before curing occurs.

Usage recommendations

Use protective gloves and eye protection when handling polyurethane foam. Store cartridges and the applicator in a cool, dry place and follow safe disposal instructions for empty or blocked cartridges. For best results, use foam formulated for the specific temperature and humidity conditions of your project and perform a small test bead to set the desired flow before full application.
