SATA 11903 / 11904 Wobble Extension Bar 1/4" Drive 2" & 4"
Tidak dapat memuatkan ketersediaan pengambilan
Product Overview
The SATA 1/4" Dr. Wobble Extension Bar is a versatile drive accessory designed to solve two common problems at once: reaching fasteners set at an angle, and extending your ratchet's reach into deeper or recessed spaces. Its unique dual-function design allows the socket end to pivot and "wobble," so you can turn fasteners that aren't perfectly in line with your ratchet — and once the socket is seated, it holds steady and functions just like a standard extension bar. Built with SATA's durable, precision-machined construction and a knurled grip section for secure handling, this extension bar is available in 2" (50mm) and 4" (100mm) lengths to suit a range of jobs.
Key Features
- Dual-function wobble design — turns off-angle fasteners, then acts as a standard extension once seated
- 1/4" square drive — compatible with standard 1/4" drive ratchets and sockets
- Knurled grip section — secure, comfortable handling during use
- Durable chrome-finished construction — built for repeated daily use
- Available in 2" and 4" lengths — flexibility for different reach requirements
- SATA lifetime warranty — backed by a globally trusted professional tool brand
