Stahlwille SW509W/2 1/2" Drive Wobble-Drive Extension Bar, 52 mm

The Stahlwille 509W series are 1/2" drive Wobble-Drive extension bars in three lengths from 52 to 130 mm. The drive swivels up to 15° each side of the centre position, with a maximum load of 200 N·m (manufacturer-stated).

The swivel lets the socket sit slightly off-line from the bar, which helps when the fastener and the ratchet cannot be lined up exactly. The material is chrome alloy steel, chrome-plated.
