Long case or Grandfather clock suspension used at the top of the pendulum which flexes allowing the pendulum to swing freely. Fitted with a single brass end which is riveted through the steel strip to retain it in the back cock.The opposite end is left plain allowing it to be cut to the correct length. A hole is drilled or punched and fitted to the original bottom block.
The strip is manufactured from hardened and tempered high carbon spring steel strip which is manufactured in the UK. Please do not confuse these with the vast quantity of cheap low quality imported suspensions that are being brought into the country which are not made from the correct materials and fail very quickly. The suspension should last many years if treated with care when removing the movement.
The strip dimensions are 0.15mm thick x 6.27mm wide x 117 mm long.
