Seals the mounting holes in your roof when the Slimline II Rack and Foot Rails are removed. Secures into your roof using the supplied M6 screws, and a flip over cap covers the screw head. The soft, yet durable, seal screws down tight, conforming to the surface of your roof to keep the elements out. Roof seals are easily removed when reinstalling the Slimline II Rack. Includes fitting instructions. Note: Works only where M6 bolts are used to secure Foot Rails and is not compatible with the Toyota Hilux Revo
