Britool England 3/8" Drive 4pc Extension Bar Set 75-450mm Made in UK

This genuine Britool England 3/8" Square Drive Extension Bar Set is manufactured from high-quality alloy steel and represents original UK-made Britool tooling, produced before the closure of the historic Britool manufacturing plant. As genuine British-made stock becomes increasingly difficult to source, these extension bars are now highly sought after by collectors and professional users alike.

Each extension bar is precision engineered to provide dependable strength, accurate fitment, and reliable torque transfer. The square drive features ball retaining grooves on each face, ensuring sockets remain securely attached during use while remaining quick and easy to change.

Covering four popular lengths, this versatile set is ideal for reaching recessed or awkward fasteners in automotive, engineering, and general workshop applications.

Due to the limited availability of original Britool England stock, this set is offered while supplies last.
