PRODUCT SPECIFICS: Two Portable Telescopic Support Legs (patented as Ladder Stabilization Support Assembly - US Patent No.10865602) designed for various extension ladders (with a variety of different ladder heights from 6 ft all the way up to 35 ft) to prevent these ladders from lateral swaying, tipping, overturning, bouncing up or down movements or slipping off the supporting grounds - a must have for climbing high elevations. Built to take advantage of a lightweight t-slotted aluminum profile (2020 Series) to telescopically extend or retract via a smooth wobble-free telescopic sliding mechanism. Endless number of pivotal, swivel and length adjustment positions to effectively level and support the ladder on any uneven supporting grounds. Can function as a ladder leg leveling extender when the telescopic support legs remain in folded position to level the ladder side rails on any uneven ground steps (such as stairs). Each Portable Telescopic Support Leg measures in length from 5.5ft (when fully retracted) to 9.2ft (when fully extended) and weighs around 4.2 lbs. All structural components are light-weight aluminum alloys with attractive clear anodized finish. State of the art adjustment control levers and handles. Most of the fitting and fastening hardware is stainless steel. Tools-free installation and setup - no need for drilling installation holes or make any other modifications to your ladder. Quick and easy mount or dismount on or off the ladder side rails. Engineered to fit all aluminum or fiberglass Werner extension ladders (may also be adapted for use with other ladders such as Louisville extension ladders, folding Luisladders, etc...). PACKAGE DETAILS: Package contains: Two fully assembled and ready to install Portable Telescopic Support Legs (ladder is not included). Package dimensions: 72 x 6 x 6 inches. Package weight: 10.4 lbs.
