FEATURES 1. EXTRA-WIDE COMFORT STEPS At 3.12" wide, the steps on the Sentinel are already comfortable, but the very top standing steps is where the Sentinel really shines. The top rungs is set at 6.25" for maximum foot comfort while standing atop the ladder. 2. GROUND CUE Many injuries occur when descending the ladder, specifically by missing the last rung of the ladder. When you step on the bottom rung of the ladder, Ground Cue makes an audible click, alerting you that you have reached the bottom step safely. 3. RAIL LOCKS The Sentinel's easy-to-use Rail Locks keep rails together while in the leaning position, storage and transit, and can easily be released for use in the stepladder position.   ROTATING WALL PAD The crowning gem of the King Kombo is its rotating wall pad. Now, you can safely set up your ladder on inside and outside corners, walls and studs with ease.   Available in 10 ft and 12 ft. Non- conductive fiberglass. A-frame • Osha compliant leaning ladder.
