Product color: As shown in the figure Product material:Stainless steel product features: Testing: Without attaching the rubber to the Bow Piece, follow steps 3-4, then flip the Bow Piece to check if the curvature of the bow Bow Piece matches that of the Bow Piece (ensure there is no significant between the bottom of the rubber attachment area and the bow Bow Piece). If a noticeable exists, increase the rotation force appropriately until the curvature aligns, then proceed to step 6 to remove the bow Bow Piece. Attaching the Rubber: Apply adhesive to one side of the Bow Piece and the rubber (or test rubber). Attach the rubber smoothly. Installing the Bow Piece: Hook the bow strings on both sides of the bow Bow Piece around the racket handle, ensuring the rotating buckle faces upward. Fit the bow Bow Piece onto the outer edge of the Bow Piece and secure the rotating buckle (the buckle should be installed at the junction of the handle and the Bow Piece). Tightening the Bow Strings: Press the rotating knob and turn it clockwise to tighten the bow strings while adjusting the bow Bow Piece position to maintain symmetry. Apply the same force used during testing to ensure the bow Bow Piece curvature matches the Bow Piece curvature. Cutting the Rubber: Flip the Bow Piece so the rubber faces upward. Use a rolling pin to press and cut along the edge of the Bow Piece from right to left (tilt the rolling pin outward; avoid pressing it inward against the Bow Piece) until the cutting is complete (left-handed users may cut from left to right). Removing the Bow Bow Piece: After cutting, flip the Bow Piece, pull up the rotating knob, and separate the bow Bow Piece by pulling it apart to both sides. Then remove the rotating buckle and take off the bow Bow Piece. Repeat the above steps to cut the rubber on the other side. Precautions: 1.
