This locking caster assembly replaces a worn or damaged wheel brake to keep your appliance stationary during use. It restores the caster's locking function for safer, more stable operation. What it does:

• Locks the appliance wheel to prevent unwanted movement while in use
• Replaces a broken, bent or non-locking caster wheel
• Helps stop an appliance that drifts or moves on smooth floors
• Matches the OEM part name and mounts in place of the original brake caster

• Disconnect power and empty the appliance before working; unplug or shut off power at the breaker
• Support or tilt the appliance per the manufacturer instructions to access the caster area; get a helper for heavy units
• Remove mounting fasteners and swap the old caster for the new unit; reuse fasteners only if in good condition
• Test the wheel and locking mechanism after installation to ensure the brake engages and holds

This ground screw secures the appliance grounding conductor to the chassis for a reliable electrical ground connection, helping maintain safety and proper operation. It's a direct-fit fastener used where a dedicated ground screw is required. What it does

• Fastens the grounding conductor to the appliance frame to maintain a secure earth/ground connection.
• Helps prevent electrical shock and reduces risk of stray voltage on the chassis.
• Addresses symptoms like intermittent or absent grounding and loose or corroded ground connections.
• Used wherever the original equipment grounding screw has been lost, damaged, or corroded.

• Disconnect power at the breaker and unplug the appliance before starting any work.
• Only attach to designated grounding points on the chassis; ensure the mating surface is clean and free of paint or corrosion.
• Use the correct driver and moderate hand torque—do not overtighten to avoid stripping threads.
