- Identify the desired location on your 1.5-inch diameter rack tubing where the clamp will be installed.
- Loosen the T-handle tension screws on both sides of the clamp by turning them counter-clockwise until the jaws open sufficiently to fit around the rack tubing.
- Position the clamp around the rack tubing.
- Hand-tighten both T-handle tension screws by turning them clockwise until the clamp is snug against the tubing.
- Ensure the clamp is level and in the correct orientation before fully tightening.
- Apply firm, even pressure to both T-handle tension screws to secure the clamp firmly in place. Do not overtighten, as this can damage the rack tubing or the clamp.
- Attach your desired drum hardware (e.g., cymbal arms, tom mounts) to the open end of the clamp, securing it with its respective fastening mechanism.
3. Operating
Once installed, the DW DWSMRKC1515 Rack 1.5-Inch Clamp provides a stable mounting point for various drum and percussion accessories. Its dual-jaw design allows for versatile positioning and secure attachment.
- Adjusting Position: To reposition the clamp, slightly loosen the T-handle tension screws, adjust the clamp to the new desired location, and then re-tighten firmly.
- Attaching Accessories: The secondary opening on the clamp is designed to accept standard drum hardware posts or arms. Insert the accessory and secure it using its integrated tightening mechanism.
- Stability Check: Periodically check the tightness of all screws and bolts to ensure maximum stability during use. Vibrations from playing can sometimes cause fasteners to loosen over time.
4. Maintenance
Regular maintenance will help preserve the functionality and appearance of your DW DWSMRKC1515 Rack 1.5-Inch Clamp.
- Cleaning: Wipe the clamp with a soft, dry cloth to remove dust and fingerprints. For more stubborn grime, a slightly damp cloth can be used, followed by immediate drying. Avoid abrasive cleaners or solvents.
- Lubrication: Occasionally, a small amount of light machine oil can be applied to the threads of the T-handle tension screws to ensure smooth operation.
- Inspection: Regularly inspect the clamp for any signs of wear, bending, or cracking. Ensure all moving parts operate smoothly.
- Storage: When not in use, store the clamp in a dry environment to prevent corrosion.
