Campers are often foreseen with some practical louvred windows, that consist of different louvres placed one above another in a frame. After many years the seals can get damaged by UV rays and heavy duty and they need to be replaced in order to prevent leakage and damages by one to another striking louvres. From now on BBT can present these seals in a set for 1 window from stock for Type 2 -07/67 under # 7414-100 and for Type 2 08/67-07/79 under # 7514-100.
