As you can see from the photo below, Loop Loc safety covers are built super-strong and securely anchored into the deck; Loop Loc puts an unbreakable "lock" on your pool to protect your family. Only Loop Loc comes with the patented SAFEDGE® and GAPGUARD® Child Safety Intrusion Barrier. It closes the dangerous gaps created where raised obstructions meet the cover's edge, so there is no way children or pets can slip through! Call us today for more information.
