  • Insect screen attachment apparatus for vehicles
    Patent number: 4836598

Each screen bracket includes a first leg for mounting the screen bracket to the support leg of the bug shield and a second leg having a male snap thereon for receiving a corresponding female snap on the bug screen. The male snaps do not penetrate the shield member of the bug shield and therefore do not weaken or otherwise deface the bug shield.
