    摘要: A leg of adjustable length, for scaffolding, has an externally screw threaded leg member slidably received in an upright tubular scaffolding member the lower end of which abuts a nut on the leg member rotatable to provide fine adjustment of the leg length. The nut has a lever arm and is tiltable to disengage its screw threads from the screw threads of the leg member to provide for coarse adjustment of the leg length. The tubular scaffold member normally seats in a recess in the nut to prevent tilting of the nut.
