Product Information
Full details
The Zipbolt Straight Slipfix is a specialized hardware solution designed for professionals and DIY enthusiasts installing handrails between two newel posts in landing applications. Its primary benefit is the provision of a secure, concealed joint that eliminates the need for unsightly cover caps or external fasteners, resulting in a clean, professional finish. While it offers superior strength and ease of use, it requires precise drilling and alignment to ensure the internal mechanism functions correctly within the handrail.

FAQs
Can this be used for stair railings on a rake?
No, this specific kit is engineered for straight-line landing applications.
What tools do I need for installation?
You will need a drill, an 8mm or corresponding size bit for the cavity, and a cordless drill with a 5mm hex bit.
Does this kit include everything needed for one joint?
Yes, the BP13.800KIT provides all the necessary components for a single straight handrail-to-post connection.
Will the hardware rust if used near a window?
The Zipbolt is intended for interior use. If exposed to significant humidity, consider sealing the handrail ends properly.
Is it possible to remove the handrail later?
Yes, the system is reversible; simply reverse the drill direction to loosen the connection if the rail needs to be replaced.
Troubleshooting
The bolt will not tighten the rail against the post
Ensure the gearbox is seated properly in the access hole and the shaft is fully engaged with the keyhole plate.
Mechanism spins without pulling the rail
Check that the 5mm hex bit is fully inserted and the bullnose is not obstructed by wood debris or internal rail architecture.
Rail feels wobbly after installation
Re-access the gearbox and turn the driver clockwise to apply more tension. Ensure the end of the handrail was cut perfectly square.
Pros and Cons
Pros
- Clean, seamless appearance without exposed hardware
- Fast installation process compared to traditional glue-and-screw methods
- Allows for future adjustments or tightening if wood settles over time
- Strong, secure mechanical lock that prevents rail wobble
Cons
- Requires precision tool work to bore the housing correctly
- Not suitable for curved handrail configurations
- Limited forgiveness if initial drill holes are misaligned
Setup, Compatibility & Care
To install, ensure your handrail is cut to the exact length required for the gap between newel posts. Use a spade bit or Forstner bit to create the access cavity in the handrail, ensuring it is deep enough to house the gearbox mechanism. When tightening, always use a 5mm hex bit; ensure the `8mm hexagon bullnose` is fully seated to prevent slippage during operation. The system is designed for interior timber handrails. Periodically inspect the joint after the first season of climate change, as wood may naturally expand or contract; if the rail feels loose, simply access the gearbox and tension the bolt further to restore rigidity.
