What material is the tower bolt made from?
The tower bolt is constructed from carbon steel.
What is the finish of the tower bolt?
The finish is Hot Dipped Galvanised, providing excellent protection against corrosion.
Can this tower bolt be used for external gates?
Yes, its hot-dipped galvanized finish and corrosion resistance rating make it suitable for external gates and shed doors exposed to the elements.
What is the bolt throw?
The bolt throw is 50mm, indicating how far the bolt extends to secure the door or gate.
How do I clean and maintain the tower bolt?
Clean with a damp cloth. Periodically check for smooth operation and consider applying a light oil to moving parts for optimal performance, especially in exposed conditions.
Troubleshooting
Bolt is stiff or difficult to slide.
Ensure the keep plate is perfectly aligned. Check for any obstructions. Clean the bolt mechanism and apply a light lubricant.
Bolt does not fully engage.
Verify the keep plate is positioned correctly to receive the bolt. Ensure no part of the door or frame is interfering with the bolt's path.
Rust or corrosion appearing.
While designed for corrosion resistance, prolonged exposure to extreme conditions may require cleaning and re-application of a suitable protective coating if significant deterioration occurs. Ensure all exposed screw heads are also protected.
Keep plate feels loose.
Tighten the screws securing the keep plate. If the wood is soft, consider using slightly larger screws or wood filler.
