Why this one
Adjustable length handle
The telescoping shaft lets you set the working length anywhere from 250 mm (approximately 9.8 inches) to 356 mm (approximately 14 inches).
Fine-tooth mechanism
With a count of forty-one teeth in the ratcheting head, the arc swing needed between clicks is minimal, making this wrench well suited for quarter-turns in cramped engine bays and confined spaces where a wide sweep is impossible.
Versatile socket compatibility
The three-eighths square output accepts any standard socket, extension bar, or adapter in that size, so this handle integrates with the sockets and accessories you already own.
Built for real work
This is an individual wrench, not a bundled kit, so you buy exactly the size you need.
Professional-grade design
Teng Tools products are engineered for daily trade use and backed by a focus on quality, fit, and function.
Read the full description
When a standard-length handle leaves you short on torque or reach, the Teng Tools 3800-41E gives you the ability to adjust on the fly. The telescoping shaft moves from 250 mm to 356 mm, letting you match the moment arm to the job instead of reaching for a cheater pipe or a separate long-handle tool.
Forty-one teeth in the head keep the arc swing tight, so you can work fasteners in confined areas where only a few degrees of rotation are available. A directional lever on the head reverses the action instantly, and the mechanism engages positively in both tightening and loosening modes.
Because this is a single tool rather than part of a pre-packaged kit, it fits the tradesman who already owns other sizes and simply needs to add or upgrade one position. The three-eighths square output connects to the sockets, universal joints, and adapters you already carry, so there is nothing else to buy.
Whether you are servicing engines, pulling interior trim panels, or working under a dashboard, the adjustable length means fewer trips back to the box. Compact when you need access, extended when you need leverage — one handle covers both requirements.
Teng Tools designs every product for the demands of professional workshops. This handle is built to deliver repeatable, reliable performance across long service intervals, shift after shift.
