  • Patent number: 4580661
    Abstract: A gutter protection device for preventing damage to an eaves-mounted gutter against which a ladder is leaned. A polyethylene foam block forms the body of the device. A semi-circular recess in one face of the body can be fitted on the lip of the gutter. A pair of pins which project from the body into the recess are then hooked behind the gutter lip to mount the device on the gutter. A bearing surface of the body has a pair of slots which receive the legs of the ladder. One slot closely receives the leg of the ladder to assist in preventing sideward sliding of the ladder. The other slot is oversized so that it can receive the legs of ladders having various sizes.
