Ideal Security's Ladder-Aide SLM is the quickest, easiest, and safest way to use your single and extension ladders on stairs. It's a compact and portable unit that doesn't require permanent installation on your ladder, can easily be moved from stair to stair, and can be used with single or extension ladders. With an anti-skid surface and micro-adjustable height (to within 1/8 inch), our ladder stabilizer for single or extension ladders create a stable, level base for use on stairways. Its rugged steel construction means it's built to last. The Ladder-Aide SLM meets the size and weight standards of Type III and Type II single and extension ladders, good for most homeowners and painting contractors. It is cost-effective, easy to set up, and small enough to be a permanent and indispensable addition to your toolkit. Meets and exceeds ANSI-ASC weight standards for ladders (ANSI-ASC A14.8-2013) and complies with the 9.1.1 Foot Slip Test.
