Professional Installation Recommended: While experienced DIYers can install this jack, proper mounting, hydraulic line routing, and electrical connections are critical for safe operation. Improper installation can damage your trailer frame or create safety hazards. Frame Requirements: Your trailer must have adequate structural support at the mounting location. The 20" mounting bracket distributes load across the frame, but consult your trailer manufacturer if you're unsure about frame strength. Power Requirements: This jack requires a dedicated 12-volt DC power source. Verify your trailer battery can handle the amp draw before installation. Do not connect to your tow vehicle's electrical system while operating the jack.
Horse Trailers: Bumper pull and gooseneck horse trailers benefit from the powerful lifting capacity and large foot pad that stays stable on soft ground at shows and farms. Cargo Trailers: Enclosed cargo trailers carrying equipment, tools, or inventory gain effortless coupling with hydraulic operation instead of manual cranking. Equipment Trailers: Heavy equipment haulers, flatbeds, and utility trailers get reliable support with the 12,000 lb capacity and rugged construction. Gooseneck Trailers: While designed primarily as a tongue jack, some gooseneck trailer owners use this jack for additional front support when unhitched for extended periods.
Installation Steps (Professional Installation Recommended): 1. Select Mounting Location: Position jack on trailer A-frame where there's adequate structural support. Measure to ensure 35" retracted height provides ground clearance. 2. Install Mounting Bracket: Attach 20" universal bracket to trailer frame using supplied hardware. Ensure bracket is level and properly torqued. 3. Mount Jack Assembly: Secure jack to mounting bracket. Verify foot pad has full range of motion and doesn't contact trailer components. 4. Install Pump/Motor: Mount pump assembly to front of jack (standard) or remotely mount in protected location if preferred. 5. Route Wiring Harness: Run wiring from jack to battery location, keeping wires away from hot exhaust, sharp edges, and moving parts. 6. Install Control Box: Mount weatherproof control box in accessible location. Connect wiring harness to control box. 7. Connect to Battery: Wire control system to dedicated 12V battery with appropriate fuse protection. Do not connect to tow vehicle electrical. 8. Test Operation: Cycle jack through full range of travel. Verify manual override access hole is clear and 6" hex bit fits properly.

The SQI24-IMO single jack is ideal for bumper pull trailers where a center-mounted jack provides adequate support. For gooseneck or fifth wheel trailers requiring dual landing gear, consider Bigfoot's landing gear systems with synchronized dual jacks.
The manual override feature is essential insurance against power failures. While not a fast operation, it ensures you can always raise or lower your jack in an emergency. Access the hex drive through the hole in the top of the tank assembly and use a standard cordless drill with the included 6" hex bit.
