The JNP range of duct access doors is designed to provide easy and speedy access to smoke, fire and volume control dampers, coils, filters and other air conditioning and ventilating equipment mounted inside ductwork.
The range of five sizes have been carefully selected to provide different degrees of access from single handed to head and shoulder entry.
JNP access doors are of double skin "sandwich" construction complete with 20mm thick high density insulation and are sealed to prevent any insulation migration.
The one piece mounting frames are pressed for accuracy and pre-punched on inner and outer flanges.
This feature allows doors to be installed so that a flush finish is achieved on plain or insulated ductwork.
All sizes of door are fitted, as standard, with a retaining chain between the door and frame.
