Ladder Stabilizers are a great choice for jobs that require extra stability or when you need the top of the ladder to break away from the wall, greatly increasing the of working at heights. (Applicable ladder outside width is 12.5-17.7 inches, please measure your ladder outside width size before purchase.) 2.[AVIATION-GRADE ALUMINUM] ladder stabilizer is specifically designed to enhance your when using a ladder. Our stabilizer is made of aviation-grade aluminum, which is lighter and more durable than other steel and iron stabilizers, and can withstand a weight of 380 LBS. The special tool placement design allows you to easily find the appropriate tool while working at height. (Not for fiberglass ladders) 3.[SUPER STABILITY]The supports at the bottom of the stabilizer are equipped with non-slip rubber feet, which ensure that they are firmly fixed on the top of the ladder during use, prevent the ladder from sliding, and improve the stability and of the ladder, reducing the risk of ladder shaking and tilting. 4.[EASY TO INSTALL & DISASSEMBLE] ladder stabilizer is easy to install and does not require any additional tools or skills. Simply install it on the top of the ladder, and when you want to disassemble it, pull down the spring locking buckle. When using it, simply place the support in the desired position and you can start working.
