The cover-for-cover (K 16505) is a secondary protective element that sits over the primary damper-end cover (K 16501), offering an extra barrier against impact, spray and environmental exposure. Often used where splash, debris or mechanical contact are likely, this outer cap increases overall assembly durability and simplifies field servicing by protecting the primary seal and fastenings. In short, K 16505 is a low-profile but effective armor layer that helps keep the damper assembly functioning cleanly and reliably over long operational cycles.
