Small end fitting, designer to fit inside our plastic solid and flexible ducting.
Plastic ducting couplers are manufactured from flame retardant polymer.
Excellent service from ordering to delivery.
Good basic extractor fan. Plenty of power and the shutters prevent back draughts. Packaging was poor causing some slight damage and the fan may have been dropped as some of the shutters and activator had fallen out of the mountings. Would recommend as value for money and gets the job done.
Brilliant product, speedy service as well as an excellent price
quality item easy to fit and delivered from a supplier I would use again
