A Double Open End Spanner, otherwise called a twofold finished spanner, is a sort of hand instrument utilized for fixing or slackening latches like stray pieces. It highlights two U-formed openings at each end, with various sizes on each side. This plan permits the spanner to grasp two inverse appearances of the latch, giving adaptability in taking care of different sizes of stray pieces. The finishes of the spanner are commonly calculated at around 15 degrees to the longitudinal hub of the handle, empowering simpler access and mobility in bound spaces.
