Installation into Wood

1. Mark and Drill

   • Drill a pilot hole of Ø 11–12 mm depending on wood hardness.

   • Ensure hole depth matches the full length of the threaded shaft.

2. Install the Shaft

   • Screw in the shaft using a wrench or the Zipbolt 40.540 Deep Socket Tool.

   • Leave approximately 14 mm (9/16 in) shaft center exposed for housing alignment.

3. Mount the Post

   • Position the newel post over the shaft.

   • Insert the diecast gear housing into the post and align over the thread.

4. Tighten the Housing

   • Using a T40 Torx bit or 5 mm hex bit, tighten the gear housing with a cordless screwdriver.

   • Do not use an impact driver to avoid over-tightening.

5. Final Check

   • Verify that the post is aligned and securely fastened.

Installation into Concrete

1. Drill and Clean the Hole

   • Bore a hole slightly larger than the external thread and to the required depth.

   • Blow or vacuum all dust and debris from the hole.

2. Apply Epoxy

   • Fill one-third to one-half of the hole with epoxy resin adhesive.

3. Install the Shaft

   • Insert the Super UT shaft, ensuring correct height alignment.

   • Wipe away excess epoxy and allow to set per adhesive manufacturer’s instructions.

4. Attach and Tighten

   • Once the epoxy has cured, assemble the post and tighten the gear housing as in the wood installation steps above.

5. Finish

   • Plug the access hole if desired and confirm the connection is solid.

Tips

• Always ensure correct shaft center alignment for tight gear engagement.

• For concrete installations, use a high-quality structural epoxy.

• Avoid overtightening to prevent gear housing damage.
