Radolid® Protection Caps
Radolid® Protection Caps are used to eliminate corrosion of nuts and bolts and allow quick removal when necessary. These caps are easily installed by pressing the cap onto the bolted joint by hand. Radolid® Caps barbed edges snap in place, preventing the caps from accidentally being removed.
Radolid® Caps are manufactured with low density UV-resistant polyethylene and are reusable and ca be reapplied 2-3 times. To ensure against corrosion from condensation accumulating in the caps, we recommend brushing nuts with Kleergel® Corrosion Inhibitor Grease. Radolid® Protection Caps will keep nuts and bolts corrosion free for years.
