Base Mate The Base Mate ladder stabilizer attaches to most wood, aluminum, and fiberglass extension ladders for a stable, extra-wide footprint that self-levels on most surfaces. The device is easy to operate, the company says–tap the release lever and let the weight of the ladder drop, and the foot slides into position. The hardened steel leg exceeds Type 1A ladder requirements. Base Mate adds less than 7 pounds to the weight of the ladder. 604.512.1238.
