SOUNDOWN Aluminum Insulation Pin & Keeper 2-1/2″ – HPA25K

The Soundown HPA25K aluminum insulation pin and keeper is used to secure acoustic insulation, foam, and barrier composite materials in marine engine compartments and other sound-control installations. The 2-1/2″ pin length is suitable for thicker insulation panels and overhead applications such as the underside of an engine hatch.

• 2-1/2″ aluminum insulation pin and keeper for Soundown installation work
• Helps fasten sound insulation where screws are not practical or desirable
• Keeper/washer spreads load across the insulation surface to help prevent tearing
• Suitable for engine boxes, hatch undersides, bulkheads, and hull interior surfaces
• Useful for small installations, repairs, and adding extra support to adhesive-mounted panels

This pin and keeper is a practical fastening solution for marine soundproofing projects, especially when installing Soundown barrier composites overhead or on vertical surfaces. For best results, use with a suitable adhesive or bonded pin base system and finish exposed insulation edges with compatible foil or barrier tape.
