4. Setup and Installation
These casters are designed for easy, tool-free installation into compatible furniture. Ensure your furniture has a threaded receptacle that matches the 5/16-18 x 1" UNC stem. If replacing existing casters, first remove the old casters before installing the new ones.
4.1. Verifying Stem Compatibility
Before installation, it is crucial to verify that the threaded stem of the new OUTWATER caster matches the existing receptacle on your furniture. The stem diameter is measured over the threads.

Figure 4.1: Guide to measuring caster stem diameter. The diameter of this caster's stem is 5/16".
4.2. Installation Steps
- Prepare the Furniture: If replacing old casters, carefully remove them from the furniture legs. This may involve pulling them out or unscrewing them, depending on their type.
- Insert New Casters: Align the threaded stem of the new OUTWATER caster with the threaded receptacle on the furniture leg.
- Screw into Place: Gently screw the caster into the receptacle by hand, turning clockwise until it is securely tightened. Do not overtighten.
- Repeat: Install all remaining casters following the same procedure.
- Test Stability: Once all casters are installed, gently test the stability of the furniture before applying full weight.
5. Operating Instructions
The OUTWATER Samson Twin Wheel Casters are designed for smooth and effortless movement across various surfaces.
5.1. Movement
These casters feature a 360-degree swivel action, allowing for easy maneuverability in any direction. The twin-wheel design helps distribute weight and reduces friction, making it simple to move furniture without excessive effort.
5.2. Engaging the Brake
Each caster is equipped with a brake mechanism to prevent unintended movement. To engage the brake, press down firmly on the lever located on the side of the caster until it clicks into the locked position. To disengage, lift the lever upwards.
Always ensure all casters are either fully engaged or fully disengaged to prevent uneven stress on the furniture and potential damage.

6. Maintenance
Regular maintenance will ensure the longevity and smooth operation of your OUTWATER casters.
- Cleaning: Periodically clean the wheels and the area around the axle to remove dust, hair, and debris that may accumulate and hinder smooth movement. Use a damp cloth and mild soap if necessary.
- Inspection: Regularly inspect the casters for any signs of wear, damage, or loose connections. Ensure the threaded stem remains securely tightened.
- Lubrication: While these casters are designed for quiet operation, a small amount of silicone-based lubricant can be applied to the swivel mechanism if any squeaking or stiffness occurs. Avoid oil-based lubricants as they can attract more dirt.
7. Troubleshooting
If you encounter any issues with your casters, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Caster not rolling smoothly | Debris (hair, lint) caught in wheels or axle. | Clean wheels and axle area thoroughly. |
| Caster squeaks during movement | Lack of lubrication in swivel mechanism. | Apply a small amount of silicone-based lubricant to the swivel point. |
| Brake not holding furniture securely | Brake mechanism not fully engaged or worn. | Ensure the brake lever is pressed down firmly until it locks. If worn, consider replacement. |
| Caster feels loose or wobbly | Threaded stem is loose in the receptacle. | Carefully tighten the threaded stem by turning the caster clockwise until snug. Do not overtighten. |
