Frequently Asked Questions
What is a tower bolt used for?
A tower bolt is a simple sliding security bolt used to fasten a door, gate, or shutter from the inside. It slides horizontally into a fixed keep or staple, preventing the door from being opened. Commonly used on back doors, shed doors, garden gates, and stable doors as an additional security measure.
Is it suitable for external use?
Yes — the black finish on Perry tower bolts is suitable for external use on gates, outbuilding doors, and garden sheds. For coastal or highly exposed locations, check the finish specification for corrosion resistance.
Can I use it at the top and bottom of a door?
Yes — using two bolts, one at the top and one at the bottom, is a common method for securing double doors, stable doors, and gate leaves where a central latch is not sufficient on its own.
How do I fit it?
Mark the bolt and keep positions on the door and frame, then fix both with standard wood screws through the pre-drilled holes. Ensure the bolt slides cleanly into the keep before fully tightening. Fixings are typically not included — check packaging.
What size do I need?
100mm is a versatile size suitable for most internal and external doors and gates. For lighter applications such as cabinet or window bolts, a 50–75mm bolt may be more appropriate.
Steel with black painted or powder-coated finish. Suitable for interior and exterior use.
