Kupo wind-up stands are constructed with chrome plated steel and a geared column that enables a single operator to raise and lower heavy loads safely with just the turn of a handle. Both risers extend simultaneously at one elevation of 4.4cm per handle turn. The unique automatic self-locking mechanism is equipped to prevent the light stand from dropping unexpectedly making the operation safer. All metal parts are made of stainless steel making our wind-up stands more robust, sturdy, and with excellent resistance to corrosion.
