Soler and Palau PG-100 Fixed Plastic Grill with Steel Collar 4 inch

Fixed Plastic Grill with Steel Collar

The Soler and Palau PG-100 is a fixed plastic grill designed as an end cap for HVAC ducting in recreational vehicles. It provides a durable termination point for 4-inch ventilation runs. The integrated steel collar adds structural rigidity at the connection point. This component suits RV owners completing or repairing air distribution systems.

Duct termination and mounting

The grill functions as a fixed end cap, closing a duct run while allowing air to pass through the plastic grille face. Its steel collar slips over standard 4-inch ducting for a secure mechanical fit. The plastic construction resists corrosion in vent environments. No moving parts or dampers are included, so airflow remains constant once installed.

Sustained airflow behaviour

Under continuous operation the fixed geometry delivers steady airflow without flutter or vibration from movable louvres. The plastic grille maintains its shape across typical RV temperature ranges. The steel collar prevents duct deformation at the joint during long-term vibration. The assembly requires no adjustment after installation, providing consistent performance for the life of the system.
