This is a classic double-strap style suspension spring, a direct replacement for the common German pattern used in grandfather, mantel and standard wall clocks. The 5.0mm blade width is fixed across the range — select the size by matching the hole-to-slot (B) and spring (C) lengths of your existing spring or movement specification.

⚠️ Please check the B and C measurements against your old spring or clock's movement documentation before ordering, as an incorrect length will affect pendulum timing and swing.
