How to Use
Position the bolt: Hold the base plate against the door face and mark the fixing hole positions with a pencil.
Pre-drill pilot holes: Drill pilot holes at each marked point to prevent the wood from splitting during installation.
Fix the base plate: Screw the base plate firmly to the door using the supplied fixings.
Position the keep: Close the door and mark where the bolt end meets the door frame or post, then fix the keep plate in place.
Test the bolt: Slide the bolt across to check it engages cleanly with the keep. Adjust if needed before fully tightening all fixings.
Frequently Asked Questions (FAQs)
What is the difference between a necked tower bolt and a standard tower bolt?
A standard tower bolt uses a straight sliding rod and is designed for doors that sit flush with their frame. A necked (or cranked) tower bolt has an angled bolt head, allowing it to secure doors or gates that sit recessed within a thicker surrounding frame, where a straight bolt would not reach the keep correctly.
Can a necked tower bolt be fitted horizontally as well as vertically?
Yes. Necked tower bolts can be mounted either horizontally or vertically, depending on the door or gate configuration. This makes them suited to a range of installations, including shed doors and cupboard closures where vertical mounting is more practical.
What type of doors are necked tower bolts most commonly used on?
They are most often used on wooden gates, shed doors, outbuilding doors, and double gates - particularly where the door is set into a rebated or recessed frame. They are also used on domestic doors as a secondary security measure.
Is zinc plating suitable for outdoor use?
Zinc plating provides a layer of corrosion resistance that makes it appropriate for outdoor use in standard garden conditions. It is worth noting that zinc-plated products are not recommended for coastal or highly marine environments, where stainless steel or galvanised finishes perform better.
What size tower bolt do I need for a garden gate?
For most standard garden gates, a 150mm or 200mm bolt works well. Taller or heavier gates benefit from two bolts - one at the top and one at the bottom - to distribute the load and improve security. The bolt should be long enough to sit comfortably on the door face without overhanging the edge.
