Family business since 1941
door-line® is a RiZZ BV brand. The family business has been a manufacturer and supplier of draft excluder and sealing products since 1941, with distribution to 19 countries. Customers include professional trade for construction and industry, the hardware sector and do it yourself, but we also deliver directly to consumers through our webshop.
door-line® draft excluders are made in our own factory in Nijkerk, in the middle of the Netherlands. Brushes have been made here since it was founded by grandfather Hendrik Zuiddam and his brothers. Later, the plastic parts were added, which now form an important part of the end product.
The second and third generation is our family business, working together on increasingly better and more beautiful draft excluder products.
