Brooks 1909 Adjustable Spanner

In 1909, Mr Brooks and his son filed patent N°7709 for improvements in adjustable spanners in the form of a rather clever and simple solution for those cyclists in need of box spanners in a variety of sizes. Our new patent is an innovation upon the original, simplyfying the design and saving weight. Spanner sizes from 1-19mm are possible by sliding the two pieces. The smaller piece is also a functional tyre lever.

Occasionally, without notice, manufacturers change product design and/or specifications.
