The Magnetic Bow Clamp for Easy Storage of Your Cello Bow

The unique patent-pending technology is based on a four-magnet closure mechanism. The clamp pops open after the lever is turned and the North and South poles on both halves oppose each other; it closes automatically when the magnetic poles re-align by themselves. The magnetic Fiedler bow clamp offers:

• efficient closing with a reassuring “click”
• safe storage of your bow, held by high quality, durable and chemically neutral foam
• can be opened or closed effortlessly with one finger
• can be retrofitted to most cello cases
• uses durable fibre-reinforced plastic and Neodymium magnets, thus being free from wear

Mounting Instructions:

The assembly kit contains the bow clamp, special screws of various lengths, two self-adhesive foam pads and a hand sewn leather bow tip pouch.

You need a 3.2 mm (1/8”) drill bit, a screwdriver and a hot glue gun. Use hot glue to securely glue one foam pad on top of the bow clamp lever, and the other right behind the frog of the stored bow.
Mounting the bow clamp

• The Fiedler bow clamp is designed to be attached with one screw. Three holes are visible on the back of the bow clamp. The one in the central position is to be used.
• Drill a 3.2 mm hole in the case shell. Drill carefully, if the case has a fabric lining.
• Use the shortest possible of the supplied screws to attach the bow clamp.
• Tighten the screw carefully. The bow clamp should not bend. If it bends, the magnets won’t align properly, resulting in a weaker adhesive force.
• Hint: If the case shell is curved and there is no foam lining inside the case, there will be some clearance between the middle of the bow clamp and the shell. A washer or a piece of wood/plastic can be used to level out the curve of the shell.

Mounting the bow tip pouch:

• The leather bow tip pouch is glued into the case with hot melt glue.
• For ACCORD cases: Use the leather pouch as a template and cut out the foam lining with a sharp cutter knife. Clean the carbon shell from all glue residues (use Acetone/nail varnish remover), then glue the leather pouch right on the shell into the cutout.
• For cases with a textile lining (e.g. Musilia): Make sure to use enough hot melt glue and work quickly, in order to make sure the glue will soak the lining and stick also to the shell. Gluing the pouch right on the carbon shell is always recommended.
