Fitting Instructions: Remove old seal by cutting it down the centre with a sharp knife. Ensure all dirt etc. is removed from channel and under side retaining flanges. Cut new seal to length plus 5mm ~ 1/4" (to ensure tight seals at the ends) Carefully concave the seal allowing the retaining flanges to extend into the side retaining grooves ensuring it is inserted in the correct way. Compress new seal to insert into side retaining grooves. If any difficulty is experienced unscrew sill, slide cut old seal then insert replacement as described above. Renew sealant before screwing home.
