Description
3 Piece Wobble Extension Extender Bar Set 1/2 Inch Drive Cr-V Steel Ratchet Quick Release Socket Wrench Tool Kits — BOLTON SKU 72552.
3 piece wobble extension extender bar set for 1/2 inch drive
This DENFOS set comprises three 1/2 inch (12.5 mm) square-drive socket extension bars in lengths of 75 mm, 150 mm and 250 mm. They are wobble-type extensions: the drive end allows the socket to be entered at a small angle to the bar’s axis, so a fastener can be reached and turned when the ratchet cannot be brought square onto it. The drive ends are chamfered and carry ball detents that hold the socket in place and reduce the chance of it being dropped in an awkward position. The bars are made from chrome-vanadium (Cr-V) steel, the usual alloy specification for impact-free hand-drive accessories, and the shafts carry a diamond-knurled band so they can be spun by hand without slipping. Sizes are laser-engraved in large, high-contrast characters for identification in poor light.

Typical applications
Wobble extensions are used to reach recessed and offset fasteners in vehicle, generator and ground-support-equipment maintenance, structural and rack assembly, and general MRO work where a straight socket approach is blocked. The three-length set covers shallow, mid-depth and deep access from a single ratchet. Extensions of this class are intended for hand drive rather than impact tools.
