Abstract
A device for attachment to a ladder which enables the upper end of a ladder to be spaced from the wall of the building, span windows and/or rest on a slant roof and thus span the gutters. The device also acts as a stabilizer bar or tube to prevent slippage of the ladder laterally, gives greater stabilization to the ladder, and almost automatically positions the ladder at the correct angle of inclination away from the lower wall of a building, and generally promotes a greater margin of safety. Also, the device is readily separable after use for small compact storage.
Claims3
A knockdown antisway or stabilizer device for the upper end of an extension ladder having a pair of side rails and rungs comprising, in combination:
- a. a pair of horizontal elongated tubular members removably secured together end to end, the free end of said members being bent at right angles to said horizontal portion of said members and both bent in the same direction to form legs;
- b. a pair of U-shaped angle brackets each having a pair of spaced side walls and a connector top wall, and outwardly extending flanges on the free ends of said side walls, each of said flanges having an arcuate slot formed therein and arranged cater-cornered from each other, each side wall having opposed apertures therein;
- c. means for removably securing said brackets one to each of said members in spaced relation;
- and
- d. a pair of U-shaped bolts having legs for anchoring said brackets and members to the rails of said ladder and about the uppermost rung thereof.
