Steps

1. Mark and Drill the Handrail

   • Mark 3 mm (1/8 in) from the end of the rail.

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

   • Drill a 10 mm (3/8 in) hole to intersect the access hole.

   • Do not cut the rail angle until all boring is complete.

2. Cut the Rail Angle

   • After drilling, cut the angle of the handrail as required.

   • Deepen the 10 mm (3/8 in) hole once the angle is cut.

3. Install the Keyhole Disc

   • Drill a 25 mm (1 in) hole in the newel post to a depth of 7 mm (9/32 in).

   • Measure the intersection point (X) from the top of the rail to the center of the 10 mm hole.

   • Subtract 3 mm (1/8 in) from this measurement to mark the disc center.

   • Secure the keyhole disc with screws flush or slightly recessed in the post.

4. Assemble the Connector

   • Insert the gear housing onto the angled shaft.

   • Engage the connector tip into the keyhole disc.

   • The shaft has sufficient play for fine adjustment if trimming is required.

5. Tighten the Connection

   • Using a 5 mm hex bit or side ratchet tool, tighten the gear housing until the joint is secure.

   • Avoid using an impact driver to prevent damage from over-tightening.

6. Finish the Installation

   • Plug and sand the access hole for a seamless appearance.

   • Verify alignment and ensure a solid connection between rail and post.

Tips

• Ideal for upper angled handrail joints; for bottom rail connections, use Zipbolt 11.550 Angled Railbolt.

• Always check alignment before final tightening.

• Apply glue in the handrail end if additional bonding strength is desired.
