How to Use
Select a Strong Fixing Point: On heavy gates, fix the bolt where the timber is thickest and most solid to handle the load across a longer bolt body.
Mark and Pre-Drill: Mark all screw positions carefully and pre-drill. For dense hardwoods, use a sharp wood bit at low speed to keep pilot holes clean.
Mount the Bolt Squarely: Fix the bolt so the barrel runs perfectly horizontal. Even a slight tilt will cause binding across a 250mm throw.
Locate the Keeper Precisely: Extend the bolt fully and mark the keeper position. On a bolt of this length, use a straight edge to confirm the keeper is in exact horizontal alignment with the barrel.
Test Before Final Tightening: Fit the keeper loosely and cycle the bolt several times. Only fully tighten all fixings once smooth operation is confirmed across the full travel.
Frequently Asked Questions (FAQs)
When do I need a 250mm bolt rather than a shorter size?
A 250mm bolt suits installations where the gate post stands further from the gate leaf, on very wide or heavy gates, or where a longer keeper engagement is needed. It is also commonly used on barn doors and agricultural gates where bolt size is matched to the scale of the door.
How do I stop a long tower bolt from binding in the keeper?
Mount the bolt body first, extend it fully, then use a straight edge or spirit level to mark the keeper position. Even a few millimetres of vertical misalignment will cause a long bolt to bind. Fit the keeper loosely and test before final tightening.
Can a 250mm tower bolt be used on a barn or field gate?
Yes. Larger tower bolts are frequently used on barn doors and agricultural gates. Make sure the fixing post is in good structural condition so the keeper remains firmly held under repeated use and wind load.
What is the difference between a flat tower bolt and a necked tower bolt?
A flat tower bolt sits flush against the door face. A necked bolt has a raised or angled section that lifts the bolt barrel clear of the door surface. Necked bolts allow the barrel to clear door furniture, hinges, or uneven surfaces that a flat bolt cannot bridge.
Can I prevent a tower bolt from being pushed open from outside?
A standard tower bolt has no lock. To prevent the bolt being forced back from the outside, fit a padlock staple alongside the bolt body and use a padlock to hold the bolt in the closed position. This converts a simple latch into a lockable fastening.
Summary
