The Series 450 is suited to heavier doors which are exposed to harsh weather conditions such as marine sites, aircraft hangars, agriculture and food factories.  All the brackets, components, door tracks and channels are manufactured from high grade 316 grade stainless steel, resulting in excellent corrosion protection of sliding door assets over many years.  Our heavy duty range, the Series 450 is the answer to heavy weight sliding door applications. Frequently used for large external doors on commercial and agricultural buildings.
