Foam Gun for PU Foam Proline long with 50 cm lance — applicator gun for mounting foam

Proline long foam gun with a 50 cm lance is an applicator designed for dispensing polyurethane (PU) mounting foam with extended reach and controlled flow. The tool connects to standard PU foam cans and provides a stable, ergonomic handle and trigger mechanism to regulate foam output. Its long lance enables access to deep cavities, narrow joints, and recessed installation points while maintaining precision during sealing, insulating, and assembly tasks.

Advantages

The Proline foam gun offers precise foam metering and smoother trigger control to reduce waste and overspill. Its 50 cm lance increases reach without the need for ladders or awkward positioning, improving access to hard-to-reach areas. Constructed for repeated use, the applicator supports accurate bead formation and consistent foam distribution for both professional installers and DIY users seeking reliable application.

Suitable for

• Filling and sealing gaps around window and door frames
• Insulating cavities and joints in walls and ceilings
• Installing and fixing frames, panels, and trims
• Applying foam in deep, narrow, or recessed spaces

Key specifications

• Lance length: 50 cm for extended reach
• Application: compatible with polyurethane (PU) mounting foam cans
• Control: adjustable trigger for precise foam flow regulation
• Construction: durable metal and polymer components for repeated use
• Ergonomics: pistol-style handle for comfortable one-handed operation

How to use

Attach a compatible PU foam can to the gun following the manufacturer instructions on the foam can. Hold the applicator with the lance directed toward the joint or cavity and gently squeeze the trigger to dispense foam; adjust pressure for desired bead size and flow. Move the lance steadily along the gap to ensure even filling. After use, follow foam can and applicator cleaning procedures to prevent nozzle clogging and to maintain performance.

Usage recommendations

Use the Proline foam gun with recommended PU mounting foam types, wear appropriate protective gloves and eye protection, and ensure adequate ventilation. For best results, practice flow control on a scrap surface before working on final joints. Clean the gun promptly after use according to the foam manufacturer's guidance to preserve the lance and valve mechanism.
