Setup and Installation
These rubber feet are designed for easy installation on various equipment. The included screws are specifically sized for the Otari MX-5050, but the feet can be installed using other methods depending on your equipment.
Installation Steps:
- Prepare the Equipment: Ensure the equipment is powered off and disconnected from any power sources. Carefully place the equipment on a stable, clean surface, allowing access to the mounting points for the feet.
- Remove Old Feet (if applicable): If replacing existing feet, carefully remove them. Note the type of fasteners used (screws, adhesive, etc.) as this may guide your new installation.
- Position the New Feet: Align the new rubber feet with the designated mounting holes on your equipment. Ensure even spacing for optimal stability.
- Secure the Feet:
- Using Screws (Recommended for Otari MX-5050): Insert the provided screws through the center hole of each rubber foot and into the equipment's mounting points. Tighten securely with a screwdriver. The integrated steel washer will prevent the screw head from pulling through the rubber.
- Using Epoxy Adhesive: For surfaces without screw holes, a strong epoxy adhesive can be used. Apply adhesive to the base of the rubber foot and firmly press it onto the desired location. Allow sufficient curing time as per the adhesive manufacturer's instructions.
- Using Machine Screws/Bolts: If your equipment uses machine screws or bolts, ensure the diameter is compatible with the foot's center hole. Secure the feet using appropriate nuts and washers if necessary.
- Verify Stability: Once all feet are installed, gently test the equipment's stability to ensure it sits level and does not wobble. Adjust as needed.

Usage and Benefits
Once installed, these rubber feet provide several key benefits for your equipment:
- Enhanced Stability: The robust design and material ensure your equipment remains stable, preventing accidental movement or tipping.
- Vibration Reduction: The NBR rubber effectively absorbs and dampens vibrations, reducing noise and protecting sensitive internal components from shock.
- Surface Protection: The non-slip and non-marking properties of the rubber prevent scratches, scuffs, and damage to underlying surfaces, such as tabletops, floors, or shelves.
- Improved Airflow: By elevating the equipment, these feet can help improve air circulation underneath, contributing to better thermal management.
- Versatile Application: Ideal for a wide range of items beyond audio equipment, including speakers, air compressors, furniture, and various power tools.
Maintenance
The Western Supply Warehouse Replacement Rubber Feet are designed for long-lasting performance with minimal maintenance. Follow these simple guidelines to ensure their continued effectiveness:
- Regular Cleaning: Periodically wipe the rubber feet with a damp cloth to remove dust and debris. Avoid harsh chemicals or abrasive cleaners, which can degrade the rubber.
- Inspect for Wear: Every few months, inspect the feet for any signs of significant wear, cracking, or hardening. While durable, extreme conditions or prolonged heavy use may eventually lead to degradation.
- Check Fasteners: If installed with screws, periodically check that the screws remain tight. Loose fasteners can compromise stability.
Troubleshooting
If you encounter any issues with your rubber feet, consider the following:
- Equipment Wobbles:
- Ensure all feet are securely fastened and tightened evenly.
- Verify that the surface the equipment is resting on is level.
- Check if any feet are damaged or unevenly worn; replace if necessary.
- Feet Slipping:
- Clean the bottom of the feet and the resting surface to remove any oils or dust that might reduce friction.
- Ensure the weight of the equipment is evenly distributed across all feet.
- Screw Pulling Through:
- The integrated steel washer is designed to prevent this. Ensure you are using the correct screw size and not overtightening excessively.
- If damage occurs, replace the foot.
