How to Use

• Mark the fixing positions: Hold the bolt plate against the door at the desired height and mark each screw hole position with a pencil.

• Drill pilot holes: Drill at each marked point before screwing to prevent timber splitting, particularly on hardwood frames.

• Fix the bolt plate: Attach the plate firmly to the door using the supplied screws.

• Set the staple keep: Extend the bolt fully to determine the keep position on the frame, mark and drill, then fix the keep so the bolt slides in squarely.

• Test the action: Slide the bolt through its full range and check for any resistance. Adjust the keep if needed before final tightening.

Frequently Asked Questions (FAQs)

• When would I need a 250mm tower bolt over a shorter one?
  A 250mm bolt is best for very wide or heavy gate panels where you need a long throw to reach the keep securely. It is also used where two shorter bolts would be impractical and a single, longer bolt is the preferred solution.

• Can I use a tower bolt on a gate that swings in both directions?
  Tower bolts are designed for single-direction swing gates. They fasten against a fixed frame or post on one side only and would not function correctly on a gate designed to swing inward and outward.

• Can a tower bolt be used to secure a gate against forced entry?
  Tower bolts are not designed as security hardware. They fasten a gate in the closed position but the bolt and staple can be forced with enough pressure. For gates where security is the priority, a hasp and padlock or a dedicated security bolt offers significantly more resistance to forced entry.

• Should a tower bolt go at the top or bottom of a gate?
  Both positions have practical use. A single bolt near the top of the gate is the most common placement. For tall or heavy gates, one bolt at the top and one near the bottom gives a more secure, balanced closure that prevents the gate twisting in the frame.

• How do I prevent the gate post from splitting when fitting a large tower bolt?
  Always pre-drill pilot holes slightly narrower than the screw shank. For older or very dry timber, a touch of wax on the screw thread can reduce the torque needed and lower the risk of splitting around the fixing point.
