## Description

The Sentry 300 automatic gate opener is the first high quality, commercial grade, Do-it-Yourself gate opener. The Sentry 300 is made in the USA and powered by a 12 vdc battery with two charging options. The battery can be charged by the included AC transformer or USAutomatic's recommended solar panel kit. The solar panel option allows for remote installations and qualifies for a 30% federal tax credit. The Sentry 300's energy efficient design makes it the first, truly solar charged gate opener that can provide weeks of operation with no sun. The Sentry Plug-N-Go wiring harness eliminates the need for wiring and makes installation fast and simple, typically under 1 hour. Universal mounting brackets that allow for push-to-open or pull-to-open installation easily bolt onto most existing gates. The linear actuator provides 400 lbs of thrust and has a compression rating of 1000 lbs. Open or close time is usually 16 seconds and will not vary dramatically with gate weight. The Sentry 300 S is designed for installation on farm gates up to 20 feet in length, ornamental iron gates up to 12 feet in length and chain link gates up to 14 feet in length. A full line of solar friendly accessories are available to allow you to customize your automated gate system to your needs. The Sentry 300 S is covered by a 3 year limited warranty that repairs or replaces defective products. System includes all mounting hardware, two dual button transmitters, battery charger, AC transformer for battery charging, installation DVD, full color installation/owners manual, control box with pre-installed components, and linear actuator. Recommended battery is a Sealed lead acid, group U1 battery not included in kit.
