Steps

1. Mark and Drill the Rail

   • Use the Railbolt Drill Guide to mark the center.

   • Bore a 25 mm (1 in) hole first, then a 10 mm (3/8 in) hole.

   • Insert the Slipfix connector into the rail and verify smooth travel from left to right.

2. Prepare the Newel Post

   • Measure 28 mm (1-1/8 in) upward from the bottom of the rail position to mark the keyhole disc centerline.

   • Bore a 25 mm (1 in) hole to a depth of 7 mm (9/32 in).

   • Install the keyhole disc flush or slightly recessed into the post using pilot holes and screws.

3. Insert and Engage the Railbolt

   • With the Slipfix Railbolt pre-installed, align the rail between the fixed posts.

   • Insert the connector tips into both keyhole discs and push the handrail downward until seated.

4. Tighten the Connection

   • Using a 5 mm hex bit, tighten the gear housing by hand or with a low-torque drill.

   • Do not use an impact driver to avoid over-tightening or damaging the housing.

5. Finish and Plug

   • Plug the access hole and sand flush for a smooth finish.

   • Confirm alignment and ensure a secure connection between rail and posts.

Tips

• Ensure the shaft is flush or slightly recessed with the handrail end before installation.

• Always verify alignment before final tightening.

• Railbolt Drill Guide is available for precise hole placement.
