How to Prevent Common Tower Bolt Installation Problems

Quick answer (read this first)

• Always measure and mark accurately before drilling to ensure perfect alignment.
• Drill pilot holes to prevent wood splitting and ensure screws drive in smoothly.
• Ensure the tower bolt and its ‘keep’ (receiver) are perfectly aligned for smooth operation.
• Regularly check and tighten all screws to prevent loosening and misalignment over time.

Safety first

• Always wear safety glasses to protect your eyes from wood splinters and debris.
• Use appropriate gloves to prevent cuts, splinters, or chemical exposure.
• Ensure your working surface (door, window frame) is stable and clamped if necessary.
• Keep your hands clear of the drilling and screwing path to avoid injury.
• Before drilling, verify there are no hidden electrical wires or plumbing pipes behind the wall or door frame.

Tools you may need

• Measuring tape or ruler
• Pencil or marker
• Electric drill machine
• Drill bits (sizes suitable for pilot holes and screws)
• Screwdriver (manual or electric, matching screw heads)
• New tower bolt set (including bolt, keep, and screws)
• Spirit level (for precise horizontal or vertical alignment)

Step-by-step

Step 1

Identify the optimal location on your door or window frame for the tower bolt, ensuring it doesn’t obstruct movement.

Step 2

Position the main body of the tower bolt and use a pencil to precisely mark the screw hole locations.

Step 3

Using a drill bit slightly smaller than your screw’s diameter, carefully drill shallow pilot holes at each marked point to prevent wood splitting.

Step 4

Align the main bolt body over the pilot holes and securely fasten it with the provided screws, checking for straightness.

Step 5

Close the door or window, extend the bolt fully into its locked position, and accurately mark the corresponding spot on the opposing frame for the ‘keep’ (receiver).

Step 6

Drill pilot holes for the ‘keep’ at the marked points, then attach the keep securely, ensuring it aligns perfectly with the bolt for smooth engagement.

Step 7

Test the tower bolt by extending and retracting it multiple times. It should move freely and lock securely without sticking or requiring excessive force.

Step 8

If the bolt is stiff, slightly adjust the keep’s position or gently widen its opening with a small file until smooth, unhindered operation is achieved.

Common mistakes

• Incorrect measurement and marking leading to misalignment, causing the bolt to jam or not lock properly.
• Failing to drill pilot holes, which can split the wood, strip screw heads, or make screws difficult to drive.
• Using screws that are either too short (poor hold) or too long (potentially damaging the other side of the frame).
• Over-tightening screws, which can strip screw threads, damage the material, or cause the bolt mechanism to bind.
• Neglecting to check for hidden electrical wiring or plumbing before drilling, posing a serious safety risk.

When to call a professional

• If you lack the necessary tools or feel uncertain about safely and correctly performing the installation.
• If the door or window frame is old, damaged, or made of a material that requires specialized tools or repair.
• If you accidentally encounter electrical wiring, plumbing, or any other hidden obstructions during the drilling process.
• If, after multiple adjustments, the tower bolt repeatedly fails to operate smoothly or securely, indicating a more complex issue.
