This is the only spring loaded pool safety cover anchor around that requires only one twist up and one twist down. This will fit all major manufactures of winter safety covers. These anchors are solid brass and lay flush with your deck when not in use.
Installation requires 3/4 inch or 7/8 inch masonry drill bit. Anchor can be installed in most previously drilled safety cover anchor holes, but may not be able to be used to replace only the internal components of an existing anchor.
