| The Master Pin Lock substitutes for the clevis pin at either or both mounting points of the Mighty Mule E-Z Gate Opener or the GTO/PRO 1000 series swing gate opener arm. It can also be inserted above the quick release pins in both chain brackets of the GTO/PRO SL-1000 slide gate opener.The pin lock deters theft of the opener arm but still allows the keyholder to manually open the gate when necessary. |
