    摘要: Ladder stabilizers are formed of channel members fixed at each side of a ladder below the bottom step or rung. An extendible member telescopes in each channel member outwardly to the floor and is held in such extended position by a lock pin to effectively double the supportive flare of the ladder. Such stabilizers may be supplied as an integral part of a ladder or sold separately as an accessory.
