  • The threads are black,anodized aluminum alloy
  • These Bob's Knobs will fit all C5 models except of course for those with black Phillips screws
  • With Bob's Knobs installed your factory dust cover will fit normally
  • On particular telescopes there is a small plastic cover over the factory collimation screws. In order for Bob's Knobs to be installed, this cover must be removed. Note that the cover is cosmetic only and will not affect the functionality of the scope without it
